It seems I did not read your intial email closely enough. You are likely looking for a M(a)Phee married to a M(a)cDonald... not the opposite? I don't seem to have any likely candidates in my database for a Catherine born M(a)cPhee married to a M(a)cDonald of the generation that you are searching. My Glengarry Co. database is primarily Catholic. Do you know if the male children you mention were M(a)cDonald's or some other surname?
