My ancestor Donald McTavish was born in Glassary, Argyllshire in 1765 and died in Lochgilphead in 1816. He was a "seafaringman" and he and two sons were drowned collecting seaweed for fertilizer. His wife, Mary and the other children, Neil, Hugh, Margaret, Mary, Alexander, Sarah, John and Duncan, emigrated to Canada in 1816 on the ship Greenfield and settled in Drummond Township, Lanark County. The McTavish family was supposedly from Fearnach, a village near Lochgilphead. I also have Lamont ancestors from the Isle of Mull. There is a very helpful family history website for the Isle of Mull.
