To my knowledge no one has ever found William Compton's English roots. On the familysearch site there is a William Compton born 12 April 1622 in Southbroom St. James, Wiltshire, England. I beleive this to be our William Comrton I. Lady Deborah Moody was from Wiltshire and some Comptons had married Moodys in Wiltshire. I have always thought there was a family connection between Debroah Moody and William Compton. I beleive research in Wiltshire will turn up proof of this. Familysearch is not always accurate but it is quite through. These records were taken from church records in England which is quite extensive, most English church records survived.
