General - Glen Lyon families to Canada

[csg1802]

I would like to hear from someone who is very familiar with Glen Lyon, its history, location of records, etc. to help me find out more about the families of two Presbyterian churches in Canada which are: St. Andrew’s, Dalhousie Mills, Glengarry County, Ontario (the “Round Church”), and St. Andrew’s Cote St George, Soulanges County, Quebec. These churches are about 5 miles apart. Some of the families who attended/attend these churches came from Glen Lyon / Breadalbane.  But because they settled here so early, they were long gone before the census’ were produced so I’d like to find other sources of information, whatever they may be. There are just too many people with the same names so the IGI is not much help.  The more common family names include: McNaughtan, Anderson, Dewar, McGregor, McFarlane, McGibbon, Robertson

Any help and hints are greatly appreciated
