To add a little to this. There are several places in Scotland with names that are variations of Tom a' Mhoid. (It means hill of the meeting place). There are three in Boleskine, one mentioned above which I followed for many years believing it to be the place I sought. However, while examining the Forfeited Estates Records in Edinburgh, it became obvious that mine was next to the Fort at Fort Augustus, which probably took its name from the nearby hill of that name. Hugh Fraser there was drowned in Loch Ness and is said to have left a widow with several children circa. 1763. I live in hope that Edinburgh will reveal if any of these children connect to any of the more recent records.
