Thank you for responding.
In researching my grandfather MICHAEL TYAHLA/TAHLA on ancestry.com, I came upon the obituary of your nana (ANNA TAHLA DROZDAK). I was intrigued to read that she was "born in Passaic NJ...a daughter of the late Michael and Mary Tahla." That Michael I believe is my grandfather. Mary would be his second wife, my grandmother HERMINA BLASKO being his first (they were married 1 May 1904).
Interestingly, the obituary says Anna was "a daughter" of Michael and Mary. You say Anna did not have any known siblings. I wonder if I'm bringing you solid news that she did, in the form of my father (George, born 1905 Passaic NJ) and his sister (my aunt Frances, born 1913)--the children of Michael and his first wife (my grandmother Hermina).
Please relay any details you may know about your nana (Anna) and her mother (Mary--do you know her maiden name, when/where she was married, her death date?), and please don't hesitate to ask me questions!
