I am curious as to the surnames under the Scottish Clan Ross. My grandfather's surname was Heggart. He was born in ON, Canada as were his parents. There are several other families in Ontario with the Heggart surname. Some of these families I know are from Ireland...(County Cork). My goal is to hopefully find out if my ancestors came from Scotland or Ireland. I do know that the spelling of the name "Heggart" has was listed as "Haggart" in the 1870 census. What do you know about these spellings? Unfortunately, when my grandfather immigrated to the U.S., his surname was changed from Heggart to Haggert!
