Not sure on this, but the 1901 census shows an Ann McMillan, born Aug. 12, 1838, with husband Duncan McMillan, in household #89 for Proton G-3 Page 10 sub-district, Grey County East. One of the sisters was shown in their mother’s obituary as being married to a D. McMullen, this could quite likely be the right one. They are both listed as being from Scotland, although it is possible just Duncan was.
