I also have a KOLISCH (sometimes spelled KOLLISCH) branch, >from the town
of Stupava (Stampfen, Stomfa) in current Slovakia (near Bratislava).
I have no informed explanation of the name, and am interested in what
people come up with. It has occurred to me that in Hebrew kol ish means
"every man", so it could have been a surname for a common person.
