The memorial to William George Wilson is here and gives Mabel's residence. The certificate can be downloaded:

I found this article, which didn't make sense at first:-
Chester Chronicle 14 September 1940
"The wedding took place at St. Boniface’s Church, on Tuesday, the Vicar (the Rev. D. 1. W. Phillips) performing the ceremony, of Miss Edna May Wilson, daughter of the late Mr. W. Wilson, and of Mrs. S. Warburton, and Mr. R T. Mathews, youngest son of Mr. R. T. Mathews.
The bride was given away by Mr Warburton...
...the Misses Freda and Nora Warburton (sisters)...
...the Misses Joan, Nesta and Brenda Warburton..."
Then I found that Stanley Warburton married Mabel Wilson in Q2 1921.
Cheshire BMD has Stanley twice, once to Mabel Wilson and once to Mabel Woolley, which means that the name of her father was different from her married name.
They had at least five Children:
WILSON, FREDA mmn WOOLLEY (as Tredda in 21 Cen)
GRO Reference: 1920 S Quarter in CHESTER Volume 08A Page 741

Probably married Thomas E A Ledward Q2 1958 Crewe district
Brenda Warburton

Mabel must have a lot of descendants. I think she died in Q3 1970 in Northwich district and Stanley in Q1 1983 in Congleton and Crewe district.
