On March 2, 1890, my great-great uncle Joseph Jacobs (1864-1918) married Eva Michalovsky (1869-1941). Both were immigrants, born in "Russia," and both lived on the Lower East Side of Manhattan. Joe was the brother of my great-grandma Tillie. (The certificate calls him Joal but he was Joe or Joseph on other documents.)
It was the first and only marriage for Joe and Eva. One of the witnesses was "M. Mahler," very likely Joe's brother-in-law Meyer Mahler. I downloaded this free full-color marriage cert from New York City Historic Vital Records. Looking at the three Xs and "signatures" of bride, groom, and one witness, I think the signatures were written by the same hand. (Not by the rabbi, whose handwriting is different.)
Of Eva and Joe's six children, three sadly died very young. Joe was a capmaker for years, until his health declined due to Parkinson's disease. I found him enumerated in a hospital for chronically-ill patients in the 1910 US Census, the hospital where he died in 1918.
Eva was supported by her children after Joe's death, living with son Frank until she died in 1941. Frank had been seriously wounded during his military service in World War I and he later became an advertising executive.
I discovered, thanks to an Ancestry hint, that Eva filled out an Alien Registration form in 1940. She never became a naturalized US citizen. My next step is to request a quote for that AR-2 form, with the hope of learning more about Eva's background.
