My Grandfathers second wife was Anna Marie Muellerschoen. I believe she was born in this country but her parents were born in Germany. Don't know where in Germany. Her parents had a bakery at 114 Charles Street in Allegheny City which was still being operated by them in 1903. I have an advertising calendar from 1903 which lists the business as "C. Muellerschoen". Does anyone have any knowledge of this family or the bakery? Does the site still exist? Census records have been of no help. Jeff Haberman
