Vivian Hugh Clarkson was married in Winnipeg on 24 July 1910 to Gladis Pitcher
[Manitoba vital statistics web site]. No ages or other details given.
In the 1911 census they were still in Winnipeg; Gladys, born in England, gave her age as 20 but one column has March 1890 -- or 1891: the last digit is smudged. As the census was taken on 1 June, 1891 is more reasonable if she was telling the truth about her age.
Aged 25 in the 1916 census. I have tended to assume she was the daughter of Job Pitcher of Grays Thurrock, Essex, aged 2 weeks in the 1891 census. However, a couple of others named Gladys Pitcher were born in that year (or at least aged less than 1 year when the census was taken).
In the 1931 census the Clarkson sons are in Port Arthur, Ontario, stepsons of Frank Harriet.
Can there really be a surname Harriet??
His wife Gladys is now aged 39 and apparently born in Scotland.
Vivian had also remarried by then.
Can anyone help me sort out who she really was and who was her second husband?
Then we might even be able to find out when and where she died.
