Margaret, you need to supply some dates, even if only for your own grandfather, and start with civil regt certificates so that you have the correct names and places to work your way back. Your parents' marriage cert., death certs., birth certs and bapts, then their parents' ones, etc.

The IGI has a marriage of CATHARINA ANN QUILLEASH and DANIEL CANNAN 24 NOV 1855 at Kirk Michael, and a bapt for a child with these parents: ANNE JANE CANNON 15 MAY 1859 Lezayre.
Brian Lawson's marriages has:
SHARPE, William Henry, 1911 R A1 118 to CHESWORTH, Mary.

- So the names and places are wrong, which is why you need to start from what you know from certs.

The only Maughold marriage after 1848 (until 1924) of a Catherine Quilleash (aged 22) is on 30 Sep 1897 to George Henry ADAMS (aged 26), with her father named as James Quilleash, Farmer.
