Saw your posting from last November and thought I'd connect withyou. Although I can't be of any more help than the other follow-ups, I do have a McClure ancestor in the Brandon area.
Andrew W McClure was born about 1843 and married Hannah Arneil in 1875 in Meadow Lea, Manitoba. Andrew was apparently (although I have yet to confirm any of this) one of the first schoolteachers in the Brandon area, and a farmer and newspaper editor.
Andrew and Hannah had three children: John, Joseph, and Walter. Hannah died in 1888 and Andrew died in 1937. They are both buried in Meadow Lea Cemetery.
Does any of this match your information? Please let me know if we've made a connection.
