Thank you! I've been doing some searching and cross referencing between 1881/2 business directory and one from 1890, then births w/same last names...no Jennie births matched up, but have found 4 other possibles, 1 with her exact birthdate (Blanche Levy). Now I'm working on male deaths during 1894-1899 with that surname..so far 1 is promising (Louis Levy a. 41, died Jan. 1, 1899)
I looked up synagogues in Manhattan but they were so numerous that I didn't pursue any of them...
maybe you'll have more Jennie luck than I, as I only used the last names that appeared in both directories, which wouldn't account for an employee who wasn't an owner in the business....
Thanks again for the assistance!
