But the links to Barton St David do not stop with John Adams and John Quincy Adams.
“Henry Adams married someone called Edith Squire,” Mr Butt explained, adding: “She was the daughter of Henry Squire, who was the son of a reverend, William Squire of Charlton Mackrell.
“Edith and Henry Adams… through another son of theirs, after 12 generations, we get Calvin Coolidge, the 30th president of the United States.”
Edith Adams’ sister, Anne Squire, married Aquilla Purchase, with a lineage that leads to Millard Fillmore, the 13th president.
Another sister, Margaret Squire, married a man called John Shephard, and their family tree guides to William Howard Taft – the 27th president.
It means this small corner of Somerset can claim to have the second, sixth, 13th, 27th and 30th presidents of the US traced back to it – and its nearby reverend.
