I have came across the name Burton several times. In fact a John Burton was a witness on Micajah Handcock's will. Note spelling "Handcock," later found as Hancock. This Micajah was uncle to the Micajah Hancock that married Mary Long. He died Sussex, 1808. He was marrid to Elizabeth Stockley.
I don't know if Micajah (Cajah on license) and Mary license is online. Copy was sent to me by another descendent.
