That's what made me think we might be related (even if it is ever so distantly)!
From the picture, I am guessing Sophie could have been anywhere from 16-35. It is an old B&W (of course) and it is hard to tell how old any is.
My grandmother (unfortunately deceased) wrote Sophie Tabaka abt. 1919 on the back of the pic. I am hoping one of my living relatives born about the same time as my grandmother may also remember Sophie and possibly some other Tabakas. If he does, I will let you know so we can compare notes.
