I've no known family connection.
Ontario Marriages gives the following info. Donald M. Mcintyre age 40 b. Scotland to Archibald and Mary McIntyre, a resident of Bruce Twp, Algoma married on 7 Feb 1874 Flora Montgomery, resident of Kincardine Twp, age 23, b. Nova Scotia to Malcolm Montgomery and Catherine McKenzie. Witnesses: Murdock Warbin (spelling??) and Angus McInnis. Both parties listed as Presbyterian. Marriage by license in Paisley, by John Straith.
Hope this helps.
