John - I am fascinated by the use of the name Quine in the Kewley family. Mary Quine who married Daniel Kewley of Kerrowdhoo was daughter of Robert Quine & Margaret Clague of Arderry (Onchan). I never found a bapmismal date for Mary, but she was married 1777 and died 1805. I would love to know whether your ancestors link into the above families.

Cheers, Nigel Crowe
