Hi northernexile,
Yes, it looks like we are related - in a round about way!!
Matthew Archibald Plews married Margaret Cossar. They had about 5 children that I know of, one being my great grandfather - John Cossar Plews who married Christina Ross. They had 6 children - son George Ross Plews was my grandfather, he married Robina McGie.
William Archibald Plews was one John Cossar Plews' brothers. He married Helen/Ellen Wallace - their son John Wallace Plews b. abt. 1896 married Amelia Jeanette Sutherland. Their children were - Matthew Archibald Plews, Margaret Keith Plews and John Wallace Plews.
Am I on the right track here?
Regards,
Sandi
