Dear Kara. 

My relatives came from the north of the island and were named Camaish with the anglisised version being Comish. Those from the south of the island tend to use the comish spelling. Will send you my family tree if this will help. I have traced back to Philip Camaish who died in 1849 and is buried at Patrick.

PS/ I am a different Alan Comish than the reply of the 30th June.
