Birthplaces of Anders Bengtsson and Joseph Bankson

Hope someone can help me.I have these pieces of undocumented information in my Bankson database.If anyone has the references I'd surely appreciate it.

Birthplace of Anders Bengtsson: Hanstrom Farm, Fuxerna Parish, Sweden. Where did this info come from?

Joseph Bankson, 1696-1732, born in Frederick County, Maryland.I think the years are right, but what record shows him born in Frederick County?

I've found the Bankston Forum to be so helpful with clarifying my research, hope someone has the answers to these questions!
