A Roadmap for Your Genealogy Research

It may look like a spreadsheet, but it is a roadmap. Let it point the way.

My last article talked about how helpful it is to use Ahnentafel numbers. After writing that, I worked on my grandparent chart some more. I did 2 things to make my chart better.

1. Used Proper Placement

I used each person's number to put them in the right cell of the spreadsheet. Did you notice the four colors of my grandparent chart? I gave each of my four grandparents and their ancestors a color: yellow, pink, green, and blue.

Will color-coding uncover a merger in your family history?

I did the same thing in Family Tree Maker. I tagged each of my grandparents with a color. That color spreads automatically to every one of their direct ancestors. It's a quick way to see:

• which of the more than 20,000 people in my tree are my direct ancestor
• whose branch they're on.

It also helps me see the shared ancestors of my dad's parents. Pietro Iamarino and Lucy Iamarino were 3rd cousins. I've got lots of ancestors with both yellow and pink color codes. I mark these ancestors as orange in my chart—that's a blend of yellow and pink.

The Ahnentafel numbers helped me see that I'd placed some names in the wrong color.

2. Added Placeholders

I added the right Ahnentafel number to the blank cells in my grandparent chart. It was tedious. I was typing away during conference calls all day. I finally got tired of it at the 9th and 10th great grandparent level, so I skipped around and left many cells blank. You'll find the updated blank chart here for download.

Then I realized something cool I could do with the blank cells.

Make placeholders bold so it's clear they haven't been found.

Pick any one of your known ancestors. Their father's Ahnentafel number is twice their own. And their mother's number is one more than that.

Knowing their numbers, but not their names, I can put placeholders in my chart to highlight who I need to find. For example, I added placeholders for my 6th great grandparents' parents in the 7th Great Grandparents column:

• #528 father of Costantino d'Emilia
• #529 mother of Costantino d'Emilia
• #530 father of Libera Mascia
• #531 mother of Libera Mascia

But wait, there's more! I can add placeholders for their ancestors in the 8th Great Grandparents column:

• #1056 paternal grandfather of Costantino d'Emilia
• #1057 paternal grandmother of Costantino d'Emilia
• #1058 maternal grandfather of Costantino d'Emilia
• #1059 maternal grandmother of Costantino d'Emilia
• #1060 paternal grandfather of Libera Mascia
• #1061 paternal grandmother of Libera Mascia
• #1062 maternal grandfather of Libera Mascia
• #1063 maternal grandmother of Libera Mascia

In my case, I'm unlikely to discover many of these names without access to Italian church records. But if your ancestors come from the United Kingdom and other places, you're in luck. You have a much better chance of filling in these missing names.

You know what that means? Your personalized grandparent chart is your genealogy research roadmap.

Placeholders make it easy to see who you should be searching for.

In my case, my chart shows me that I'm missing a bunch of 4th great grandparents. And they're all on my maternal grandmother's branch. I've been going hog-wild researching my paternal ancestors lately. But these 8 ancestors on my blue branch need to be a priority.

It's so easy (and fun) to go off on a tangent with your family tree building. Your grandparent chart can set you back on track. It's amazing to me that I've identified 56 of my 64 4th great grandparents. It's even more amazing to know the names of 4 of my 9th great grandparents.

Let this roadmap highlight your top-priority research areas. Think how good it will feel to complete more cells of your grandparent chart.

3 Things to Do with Ahnentafel Numbers

This numbering system takes all the guesswork out of which ancestor is which.

Did you realize each of your direct ancestors has a number? It's a number that never changes. And my ancestor #126 is the same as your ancestor #126. They're not the same person, but they are our mother's mother's mother's mother's mother's father.

We call this numbering system Ahnentafel numbers. Ahnentafel is German for ancestor (ahnen) table (tafel). Here's how it works.

In your family tree, you are #1, your father is #2, and your mother is #3. The rest follows a pattern. All male ancestors have even numbers and all female ancestors have odd numbers.

Ahnentafel numbers let me sort a column of ancestors easily.

You can figure out the numbers yourself. Let's use your father, Ahnentafel #2, as an example. His father is double his number (so, 4) and his mother is 1 more than his father (so, 5).

One of my 2nd great grandmothers is #31, so her father is double that (62) and her mother is 1 more than her father (63).

Family Tree Maker has an Ahnentafel report to figure them all out for you. Choose yourself, or anyone in your tree who you want to be #1, and run the report. But what can you do with these numbers?

Here are 3 useful things you can do with your Ahnentafel numbers.

1. Add Them to Your Grandparent Chart

I created a grandparent chart to keep track of all the direct ancestors I've identified. Here's a blank chart you can use—now updated with numbers in the cells. Some of the longer columns were getting pretty full. That's when I realized Ahnentafel numbers would help me keep the people in each column in the right order. It helps me see where the missing ancestors belong, too.

2. List Them Out

Let's say you want to see who's missing, but you don't want a grandparent chart. You can list your ancestors in numerical order, like this:

1. you
2. father
3. mother
4. paternal grandfather (your father's father)
5. paternal grandmother (your father's mother)
6. maternal grandfather (your mother's father)
7. maternal grandmother (your mother's mother)
8. great-grandfather (your father's father's father)
9. great-grandmother (your father's father's mother)
10. great-grandfather (your father's mother's father)
11. great-grandmother (your father's mother's mother)
12. great-grandfather (your mother's father's father)
13. great-grandmother (your mother's father's mother)
14. great-grandfather (your mother's mother's father)
15. great-grandmother (your mother's mother's mother)

Continue the list as far as you can until you hit a missing number. That's the closest ancestor you're missing.

Here's a simple tool to help you figure out which number belongs to which ancestor. Simply enter a number in the box to see their relationship to you, like #120, your mother's mother's mother's father's father's father.

The first ancestor I'm missing is Ahnentafel #59, my mother's mother's father's mother's mother, or my 3rd great grandmother.

I'm not missing another one until #109, my mother's father's mother's mother's father's mother, or my 4th great grandmother.

My missing 3rd great grandmother and handful of missing 4th great grandparents need my attention. If I didn't look at my tree in this way, I wouldn't know exactly who is missing.

This section of my ancestor chart shows each ancestor's Ahnentafel number.

3. Create a Custom Ahnentafel Chart

I added a new custom Ahnentafel field in Family Tree Maker. (Go to Edit / Manage Facts / New. Use Ahnentafel for the Fact label, but uncheck the boxes for Date and Place.) I can add the proper Ahnentafel number to each of my direct ancestors.

Now I can create my vertical pedigree chart and see the numbers. It's easier to see exactly who's missing in this graphical format.

No matter how you do it, think of your Ahnentafel numbers as a tool to show you where to focus your research work. I really want to find the name of my #59.

You may not think of genealogy as a numbers game, but these numbers can help you fortify your family tree. Don't miss the companion article on this topic. Plus, I found a 4th great thing to do! Make your own Elder Scroll.

5 Tips for Researching the In-Laws

When the family names and places aren't yours, how can you be sure it's them?

I wouldn't research my ex-in-laws at all if they weren't my sons' ancestors. But since they are, once in a while I check to see what else I can learn about them.

The main problem with researching your in-laws is the lack of familiarity. When it's your family, the names and places you discover are familiar. You can remember how Grandpa always mentioned the name of his hometown. You heard your mom talk about her great uncle living in a little room in her building.

But when it's not your family, you have so much less to go on. What can you do?

When my 1st son was born, I filled in a family tree chart in his baby book. My ex-mother- and father-in-law gave me the names for their side of the family. The baby-book chart only goes back as far as the baby's great grandparents. But it's a good start.

Here are 5 tips for building that less-familiar family tree.

One document after another, you can make progress on that in-law's family tree.

1. Start With the Easy Documents

Try to find the latest census record you can for the family. For me, that's the 1940 census for each of my ex-husband's parents. (Let's call them ex-Mom and ex-Dad.) This is the first step to learning more about the families.

These census pages tell me where ex-Mom and ex-Dad lived in 1940 and 1935. They confirm ex-Mom's siblings' names and that ex-Dad was an only child. Now I have the approximate birth years and birth places of their parents.

Each tidbit of information gives clues to help find more documents. Keep building on each fact you learn.

An odd little memory came in handy when I found Uncle Anton.

2. Try to Remember Details

One snippet of a memory proved to be very helpful. I remember visiting my ex-in-laws' vacation home in the 1980s. I went up to the attic to fetch something and saw an old hat. It was a black bowler hat with a sheen to it. Pinned to it was a piece of paper that said "Uncle Anton's hat".

Knowing there was an Uncle Anton helped me positively identify the family in the 1900 census. Both father and son were named Anton. Another son, John, was ex-Mom's father.

That meant I'd found another generation, plus siblings. And that led to many more documents.

A rock-solid bit of family lore—debunked!

3. Investigate Family Stories

For years we thought ex-Dad's mother's uncle was Captain Smith who went down at the helm of the Titanic. I met ex-Dad's mom. This sweet old woman was deeply ashamed that her father Walter Smith's brother was the captain. My ex-Dad even belonged to a Titanic historic association.

When my son's school friends didn't believe he was related to Captain Smith, I said, "Now I know how to prove it." So I used my new genealogy research skills and quickly learned…wait for it…Captain Smith had no siblings! That is, he had only half-siblings whose last name was Hancock, not Smith.

What went wrong there? My ex-Dad came to realize the truth, but by then, his mom had passed away.

Have you heard any family stories with a single drop of historical fact you can investigate?

4. Follow the Paper Trail

Here's where you need to be careful. Without first-hand knowledge of the family, it will be impossible to be sure of some documents.

For example, take ex-Mom's maternal grandfather Edmund. The 1910 U.S. Federal Census says he arrived in America in 1889 and was naturalized by 1910.

I found an 1889 ship manifest with a man from Ireland who is the right age and has the right name. But ship manifests in 1889 don't offer much information. How can I be sure this is my guy? For now I've saved the URL of the manifest, but I haven't added it to my family tree.

The best way to prove I'm looking at the right Edmund is to find his naturalization papers. So far, I can't find those papers.

5. Seek Out Relatives

Of course you should never trust someone else's family tree if it has no sources. But you can use it for clues.

I found a relative with a published family tree. This took ex-Dad's paternal line back several generations. Using this tree as a guide, I searched for documents on Ancestry.com to prove whether the tree was right or wrong.

With this helpful tree, I went back as far as a set of 5th great grandparents for my sons.

If you use someone else's tree for its clues, be sure to cite the tree as a source. I'm happy when I can replace that family tree citation with a more formal source (like "England, Select Births and Christenings, 1538–1975"). But until you have proof in hand, add a citation so you know where you found this detail.

While you may never get as far on your in-laws side as you do on your own, you can do it justice. Use your skills to gather every piece of low-hanging fruit. And see where it leads you.
