Sorry Susan. Your James does not appear to be connected to ours
On a rough tree, I did many years ago I had him as born 1808 Malew, the son of James Gilmour and Margaret Currie who married 1805 Malew.
Our John James Gilmour, born 1818 Kirk Michael, is the son of Daniel Gilmour (born 1796 Ireland) and Elizabeth Shimmin.who married 1818 K German.
It could be that James Gilmour the elder and Daniel Gilmour were brothers born in Ireland. I'm afraid Daniel is the furthest I can go on this line.
