Thankyou. If (and I stress if) Margaret Gawne was from Rushen then she may have been either the daughter of John Gawne and Margaret Gell (1766) or William Gawne and Joney Crebbin (1772). One of these may have married Thomas Craine in Malew 'abt 1800'. This is a personal entry in the IGI and gives her age as 'about 1775'.
