NOTES ON SURNAMES (HULL) 7
CLAPPISON According to George Redmonds, this surname developed from an earlier Clapham, which derives from a place of that name on the Yorkshire-Lancashire border. When -son names were becoming fashionable (late 14th century?) some families that already had a surname had the suffix added. So some Claphams became Claphamsons, which eventually became Clappison, Clapson, etc.
A Robert Claphamson is recorded in York, 1598 (Redmonds).
In Roos (Holderness, East Yorkshire) parish register the surnames Claphamson and Clappison occur in the mid-17th century, e.g.
