yes, same family; my parents were both born in antigo, as well as older sisters. my dad was from a family of 8, son of francis xavier and catherine wahleitner gallenberg.
in the late 1800's, my grandfather moved over to antigo from the white lake / kewaunee WI area, dropping the "er" from the name. all the relatives in antigo use 'gallenberg' while the ones to the east stuck with the 'gallenberger' ... we've done SOME research but not nearly enough. plan a trip to munich area this spring to visit the family village.
