Some of my ancestors also came from the IOM:
I have a Curphey ancestor (Isabel) born in the IOM, I imagine, in the late 1700s.
Following directly to me, she married Thomas Kinvig.
Their daughter, Eliza (b. 1815) married William Muncaster (m. 17/5/1836).
Their daughter Catherine (b. Castletown, 1845) married George Lorimer. George was a jeweller orginally from Scotland. He and his family came to NZ in 1881. I don't know the name of the ship.
Their daughter, Emily Louisa (b, Douglas 3 Jan 1870) married Richard Dilnot Gambrill on 2 Oct 1897).
