I believe these three snapshots are related to the wedding of Yvonne Durrell and Alexander Soppet in Winnipeg, Manitoba, Canada on the 24 August 1940. I did find an article describing a shower and mentioning the bride, groom and Mrs. James Shand and Marjorie Taylor.
I think it likely that Yvonne and my mother were friends, and/or that Mrs. Shand and my mum or grandmother were friends. They must have been neighbours at some point - Mrs. Shand lived at 224 Spence St. in Winnipeg and my mum lived at 270 Spence St. The photo captions are in my mother's hand.

From the Winnipeg Evening Tribune, 24 August 1940, page 10.
In honor of Miss Yvonne Durnell, whose marriage to Alexander Soppet was an event of Saturday, Mrs. James Shand and Miss Marjorie Taylor entertained at a cup and saucer shower Tuesday evening at Mrs. Shand's home, 224 Spence st. Guests numbered 12.
