I am a direct descendant of Sarah Osborne thru her marriage to Robert Prince and their son Joseph. I do not think she had children with Alexander Osborne. Joseph Prince's line went down thru the Redington's and Level's. My ancestor was Abigail Redington that married Thomas Level and they spent a lot of their adult life and death in Benton Co, Iowa. If you need help with this line I would be glad to help. VaDonna
