My name is Carlos and my wife's (Gena) great-grandmother was Marianna. I have recently been doing some genealogy for her.
We have even named our daughter after Marianna since my wife had many good childhood memories of her (she was small). There are many good memories. We altered the spelling slightly due to the pronunciation we heard from everyone around us (it was already a transliteration anyway): Mirianna.
From what I know, Elias Joseph Nassar was born 15 FEB 1897 or 5 APR 1894 (I seem to have conflicting reports).
Norma Azar (or Nora or possibly Tarsa/Tarfa [original arabic pronunciation - again I don't really know and could use the help]) was her mother.
I have heard some great stories about why she left with Elias ("the knight on the white horse") -- lots of family legend stuff.
I would also love to hear about any information that you may have. Thanks!
