I am looking for any information on my branch of the MacKay family. My grandfather was John Thomas MacKay, married to Laura May MacMillan. John Thomas was the son of William Henry MacKay and Annie Arnold White. All I know about William is that he was the son of a MacKay and MacDougall. I know that my family came from Scotland to Prince Edward Island and eventually made its way to the Boston, MA area. Any help would be much appreciated!
