Hello Liana,
This Josef Ellenbogen, my first cousin twice removed, was born in 1881 and his only daughter Hilde Renate Kaufman was born in 1918 in Vienna. She came to the States around 1940.
If you are Liana L Kilgore, Mendez born in 1971 he cannot be your 2nd great grandfather.
He was a lawyer and not a rabbi.
BTW how are you related ?
Best,
Harold
