Donald James Sillers Ancestry Scotland

Hello Sandy, I have just read that most interesting CLANS OF SHISKINE by Charles Robertson. It certainly provides a good insight into the conditions that led to families emigrating to seek better conditions. My sister-in-law is widow of Donald James Sillers, (this is the spelling the family uses now) a descendant of one of those tenants of Monyquil who sought better circumstance in Canada. "Don" is apparently the descendant of Duncan Sillars and his wife Marian Millar who came with family to Canada in 1831. I am trying to compile a family history of this Sillars line. Can you provide assistance with the family as they lived on the Isle of Arran? Contacts or sources for information? Harry A. Tatro, Calgary, Alberta, Canada.
