Hi Glenn, This is a website that has death and cencus records on many of your Sitta family. Yes, it appears that
Josef Sitta is Frank,s brother, but it looks like all the children were born in
Texas. There parents were born in
Europe, or Austria. The father, Frank, may have had a brother named John, or at least a close relative.
