Hi there.
I was wondering if you had tried contacting living relatives as was suggested in the other thread to see if you could get some info that way?
Kathryn would have been about 41 when Malcolm died and if she didn't remarry shortly thereafter the likelihood of any children from this union would be low. Also, I would expect that any children would have been mentioned in her obit.
BMD's are protected by privacy laws in Canada with marriages generally protected for 80 years or so, deaths about 70 years, and births about 100 years. The marriage index for Ontario is currently available to the public up to about 1929 with a new year added annually. Beyond these dates one must meet certain specific criteria in order to be able to order a cert. We rely on newspaper notices or other sources for BMD info beyond the privacy limits. I haven't looked at the Nova Scotia Vital Stats website. It is free to use so I will leave that to you.
I would suspect that only Kathryn or perhaps a living rellie would know why she returned to Nova Scotia.
The 1957 voter's list has a Kenneth and Catherine Mckenzie at 61 Harrison Street in Hamilton. No way to know for sure if this is your couple. I don't see them together at any other time at the moment.
