John Bickmore

So many John Bickmores! Who's the John in my niece's family tree who resisted the British in 1770s and who, with his wife, signed a petition against the king? That's the Bickmore I want to find so I can verify his Revolutionary War activities, confirm the genealogy line, and Katie can qualify for the DAR.

Here's the limb of this family tree I'm seeking to verify:

George Bickmore (b. 1705? in Norfolk Cty, MA) --> John Bickmore (b. 1731? in Suffolk Cty, MA) -->David Bickmore (b. 1764? in Meduncook, Lincoln county, Maine) -->Samuel David Bickmore (b. 1806, Friendship, ME) --> Martha Jane Bickmore (b. 1842, Nauvoo, IL).

If you've got Bickmore info, happy to exchange. Thanks!
