I was interested after having looked through the various messages on the Ancestry.com board over the Thanksgiving holiday. I actually tried to send Susan Vallejo an email, but maybe I have the wrong person.
My father's brother was a Richard Sfer, and his name was George Sfer (I was a "jr" but dropped that when I was VERY young). I never knew my father at all, but he was from the eastern PA / NJ area.
According to my mother, he was somewhat dark skinned as well and his nationality may have been Hungarian, that's a bit of a mystery even to my mother.
I thought I would just post a message as my father's background is unknown to me, except for a few general things my mother has passed along. I would be curious to hear anything from a possible relative.
