But what happened to Joe after 1905? He seems to disappear from official records, although family notes say he died in 1919. Sometimes his surname was recorded as "Jacob," sometimes as "Jacobs," which only complicates my search for Uncle Joe.
In 1905, Joe was still living at 88 Christie Street, now shown as the janitor (at right).
But after that, his wife Eva Michaelovsky Jacobs and the children are shown by themselves, living in Brooklyn, in the 1910 US Census and the 1915 NY Census. No Joe in either of these records.
In the 1920 Census, Eva Jacobs is listed as a widow living in Brooklyn. Where did Joe Jacobs spend the time between 1905 and his death in about 1919? If he registered for WWI, I can't find his paperwork. But I'm still on Joe's trail!
Common Pleas Court of New York County (see above image of index). How to obtain his actual papers? NARA doesn't seem to be the right place for a NY state court. UPDATE: These papers were not much help, only saying what the index card said (see below).
*I received an excellent comment from Steve, who says:
"Copies of local court naturalization records in New York City from 1792-1906 are held by the New York branch of the National Archives. So you should be able to order a copy of a naturalization by the New York County Common Pleas Court from the National Archives website.However, I don't think the Joe Jacobs from the naturalization index card is the same person as your Joe Jacobs. I checked both the 1900 and 1905 census records mentioned above. In the 1900 census it says that Joe had only filed first papers and had not become a citizen yet. In the 1905 census he's listed as an alien. So I don't think he could be the same person who naturalized in Oct. 1888."
Steve has a very good point--and I also appreciate knowing that I can order this naturalization from the National Archives website. I have to investigate further, but since the Joe Jacobs on the index card was living at 49 Clinton Street, and that's the exact address where Joe and Eva were living when they married in 1890, my guess is there's some connection worth pursuing. Thank you, Steve! UPDATE: As shown above, the papers provided no other information, unfortunately, so the hunt continues.
