suspect the Sharp line is from John Sharp illegitimate to John Sharp + Elizth Kewn als Clucas?
John marr Margaret Cowley San 17910514 and is buried Malew 18321213 age 88

their son Robert (bapt 1800) mar Elizth Lewin Malew 18220307 (Robt moved around as postman, letter carrier etc) + married Margt Kneen as 2nd wife (no ch to this marr)

Elizth is I think dau of Wm Lewin + Elizth Quine (I can trace the Quine link back) but several choices for Wm

the presentments for fornication at church court in 1748 are for John Sharp mariner and Eliz Kewn wife of Daniel
