I have tracked one branch of my family tree back to Joseph Jeaffreson, born about 1580 in Pettistree, Suffolk, who stayed behind in England while his brothers -- Col. John Jeaffreson (1582-1660) and Samuel Jeaffreson (1584-1649) -- sailed off to colonize St. Kitts in the West Indies. It is was from this Samuel who President Thomas Jefferson descended. But little definite info seems available about the parents of Joseph, Col. John and Samuel, or any previous ancestors. Is there a definitive Jeaffreson/Jefferson "pedigree" or family tree that pre-dates their 1624 St. Kitts voyage backward in time?? Thanks to all for your diligent research.
