I never thought there were any other Dowiats' out there either. I remember my father, Lee Dowiat, saying something of "other Dowiats'" somewhere in Illinois but I'm not certain if it was family. I believe our original name, from my fathers baptismal certificate, was Dowiatas. My Grandfather, Leopold Dowiat, also imigrated to the U.S. (Pittsburgh, PA) in the early 1900's from Lithuainia. So it's possible we could be related. Good news, or bad? I'll leave that up to you.
I don't know much about my fathers family history. I don't even have any knowledge of my Grandfathers' siblings. Well... so far I've been a great help to you, haven't I?
Please email me if you do come across any info regarding "our" ancestry.
