6 Ways to Use City Directories for Genealogy

My grandfather's 1920 ship manifest shows him as an 18-years-old arriving in New York alone. It came as a surprise that he was heading to Newton, Massachusetts. I knew he spent years in Pennsylvania, Ohio and New York City, but Newton, Mass?

The typewritten manifest says he was joining his "Uncle Pilla Di Gennaro" at 29 West Street in Newton. That wording confused me for a long time. Uncle Pilla Di Gennaro? Years later I realized this was his mother's brother Antonio Pilla, the son of Gennaro Pilla. I don't know why he didn't say he was going to Uncle Antonio, but I needed to research Antonio Pilla in Newton.

How City Directories Can Jump-Start Your Research

Take advantage of the 6 ways old city directories can help in your genealogy research.

While I was attending a genealogy conference in Boston, I researched Antonio Pilla. I began by searching the city directories for Newton. Here are the most important facts I discovered from city directories:

• Antonio's wife's name was Angelina.
• He was the manager of a company called Basilone & Co. in 1909. (Basilone is a common last name from his hometown in Italy.)
• Antonio and Angelina lived at 17 Jones Court from 1921–1925.
• He was a laborer from 1921–1932.
• They lived at 224 Chapel Street from 1927–1934, and Angelina was still there in 1940. (I never found them at 29 West Street, as listed on Grandpa's ship manifest. But West Street is one street away from Chapel Street and Jones Court.)
• The directory lists Angelina as Antonio's widow in 1936. To my surprise and delight, it includes his date of death: June 14 1934.
• The directory also lists their adult children Henry and Mary at 224 Chapel Street in 1940.
• The directory lists their adult sons Anthony and William at 224 Chapel Street in 1943 and 1945. Anthony is there in 1948, too.

The city directories formed a solid foundation for my research into this family. I went on to find:

• Antonio's 1913 immigration
• his six children
• his wife's full name and place of birth
• her 1903 immigration as a baby
• her second marriage

Angelina still lived at 224 Chapel Street in 1941 and was likely there when she died in 1963. Google Maps shows me the house still stands today. The grave marker photo on Find a Grave shows Angelina buried with Antonio, not her second husband.

Harvesting Key Data Points from City Directories

Keep an eye out for unexpected details, bad indexing, and mistakes.

I found these and other city directories on Ancestry, but you can also find them for free on FamilySearch. Search their catalog for Keywords "city directory" and the country or city of your choice.

Here are 6 ways you can use city directories for your genealogy research.

1. Find your relative's address between census years. This may help you find them in the following census.
2. Track their occupation through the years. My grandmother's uncle had a different job every time I find him.
3. Discover their spouse's name and other family members' names. Look for the inclusion of adult children living in the household.
4. If the directory says your person is as widow or widower, you can narrow down the year of their spouse's death. Or you may get lucky and see the date of death as I did for Antonio.
5. Check the back of the book for abbreviations of occupations, first names, and street names. The abbreviation "do" means ditto. Don't miss out on any details.
6. Look for a street and avenue directory to locate no-longer-existing streets.

Sometimes you'll find a ton of city directory listings in your search results. Each one is worth a closer look. But don't rely on search results alone. If you know your person might have been in a particular place at a particular time, find the directory and search the alphabetical listings. When you piece these listings together, you can discover a lot about the arc of your relative's life.
