I understand that there have been three Gilmour family trees done and they link, and have been filed with either the IOMFHS or the Museum. I remember speaking to the person who had the Ramsey branch, but as it was some years ago, I cannot remember the detail. From memory, there were not an awful lot of Gilmour's on the island back then. My man (refer Illegitimate births on these postings) was one Richard Gilmour, who denied paternity for one of my family, He was the only Richard Gilmour on the island, and was from both Glen Vine, and later Onchan (as was the mother of what I believe to be his child!)

I think you should get your answer if you look for these trees.
