Thanks for your reply! The name Sorensen just refers to the database and is not relevent here.
I now realise that I should have taken advantage of the one bit of information that the database does give: the ancestry.
I matched (very closely) with 2 Satterfields.
One's ancestry is linked to a file on the familysearch site: http://www.familysearch.org/Eng/Search/af/individual_record....
If you run through that tree you should see potential links? The oldest traced male, apparently a William, was born abt 1745 in Chowan NC and died 1813 in Pendleton SC.
For the other one, there was a Fred W Satterfield b. 1865, Chapel Hill Missouri. His son in this line was Lester T Satterfield born in Colorado.
Ring any bells?
