Do you know where the last name BUSA originally came from?

Answer 1

Hey Mike,

Swyrich.com does not have that name, so nothing from them. Family Search by LDS has 190 BUSA entries. Their entries come from Poland, Italy, the Philippines, and many places that look like where they migrated to (you can tell by the dates being more recent).

If you get really interested in finding out where your influence of BUSA came from, you may need to do your family tree branch for that name, or get a DNA test for that Surname (requires a Male participant with that last name).
