Hi my name is Brian MacKay, regarding the MacDiarmid (sic) connection, some years ago a book called "From the Farthest Hebrides" was put out by a college professor named Ferguson , whose family was of cape breton extraction, but the real author of the book was the Oral historian John A. MacDonald, a native of North Uist.He stated that "124 Irish gentlemen were sent to The Hebrides as a part of the dowry of O'Cathan's Daughter, O'Cathan(Modern day O'Kane) was an Irish chief apparently of some magnitude, for his daughter married Somerled Lord of the Isles, and the progenitor of the MacDonald's. among these gentlemen was one Gillesbuig MacDiarmad (Archibald MacDermid), according to MacDonald he was the progenitor of the MacDermid's in the Isles. he gives the year as 1306."I am not sure if it is possible to verify this information or not. but I just thought this might be of interest to you. I found this particularly intersting as the name Archibald is so pervasive in the MacDermid of scotland, one of my Grandmothers brothers was Donald Archibald MacDermid, Her mother had an uncle Archie Macdermid and the initial A. is found quite frequently in my Macdermid Ancestors, my great-grandfather Malcolm Macdermid and his wife Annie (MacDermid) were second cousins and originated in Harris and possibly Skye. Malcolm was born at Strond ,Harris in 1841. and her brother's wife was a Gillis.
