I am a descendent of Elizabeth Degournai/Degournal and Sir John apAdams. My research has shown that John Adams-b.1502-and Margery Squire are descended from Elizabeth also, with their son, Richard-b.1530-being my line. Did your Henry have a sibling named Richard? If so, he is most likely a descendent of Elizabeth and John apAdams. I have more Adams data on my line, along with our connection with President John Adams and John Quincy Adams through Margery and John's g-g-g-grandson William Adams and Miss Borrington. William's son, Henry, married Edith Squire, which is John Quincy's line. Their younger son George married Martha Streethold, which is my line.
