Whereas I am officially not a Bellin, My husband's grandmother married a Bellin in De Pere Wi.
He was the son of Dr. Henry (JR) Bellin of whom the Bellin Hospital in Green Bay was named after.
He went into medicine due to the many family heritary illnesses of the Bellin family.
If you search also for Terrien and Worachek, you will find their charts also include parts of the Bellin history from Green Bay and Luxemburg WI. These charts also include Dr. Henry, his dad Henry from Belgium etc.
