Hi Denise, I might be able to help you with who Donald might be as my own Maclean family came from Garvan and were living there in the 1840s to 1860s when Katherine MacLean my gt gt gt grandmother died there in 1868, aged 94 years. She was also born in Garvan 1774. There was another family of Macleans also lived in Garvan. Her sister Ann who also married a Maclean (Allan) she kept a croft there in 1841.Ther was also another family there that came from Ardnamurchen, Glenaladale they were Catholic also related. Can you tell me more about your Donald? What were his childrens names and in what order, then I should be able to help.
