Hi, Have you posted your quest to the Ontario Message Board: or Mail List.
There may be persons who will be able to assist re Isabella and her family husband Peter , daughter Muriel
Which in turn - may eventually lead you to information re the marriage which may have occurred in Lacombe Alberta
Always best to start with the most current information - and work back.
I know they didn't die in Lacombe but fairly sure they married there as per the form from the passenger list attached.
The last known address of the pair was 210 Alfred Street, Kingston, Ontario where all correspondence to a now deceased relative stopped. SNIP
Unfortunately we do not have a National Registry of Marriages Birth -Death in Canada
Some Provinces have the Vital Events - that they now consider Public Record online.
Alberta - does not.
All Marriages /Births/Deaths - that occur in Alberta need to be Registered in that Province.
Registration of Marriage - from Govt of Alberta Vital Statistics Registry Offices in Edmonton.
The Cost is aprox $40 Cndn. There may be restrictions to access but worth contacting Vital Stats.
Last Known Address for Peter CAMPBELL ? and Isabella CAMPBELL nee STEWART was
210 Alfred Street, Kingston Ontario.
Telephone Directory - may show the family
If a City Directory / Criss Cross Direactory [shows name to address -address to name] will show all persons living at a particular address.
Do you have the passenger list for Isabella CAMPBELL returning to Canada with adopted daughter Muriel.
It should show destination.
Isabella CAMPBELL nee STEWART had a brother John Muir STEWART - dcd 13/04/1916
did he serve with Canadian Expeditionary Forces? if so - Have you obtained Service Records
Have you obtained Service Records for your Grandfather
There might have been an obituary published - or a news story in the paper - which might mention children - also the Obituary for his wife Isabella [WHITE] STEWART - may mention names of children.
Re the Adoption: Perhaps the child of a family member ? who may have passed away during the war?
others do adopt - even when they do have their own birth child/children.
