The maternal names are linked through Bill's mother Mary Elizabeth McManus.
The McManus has a long history in the United States. Starting with the Pilgrims landing in the 1600's, where William Bradford was aboard and became the governor of Massachusetts for a few decades.
The Bradford lineage married into the Dutch family named Simonsons, who were prominent in the settlement of the Michagan territory.
