I have a note that James Comaish was baptised in Andreas on 08 Sep 1811, the son of Stephen Comaish and Isabel McNameer. There were 5 siblings, one of whom was Isabella who I believe is my 3GGM. [Source - IGI].
James married Esther Gawne and they emigrated to Australia. There were 5 children, reportedly.
I haven't checked all the data yet, so I might be wrong!
