Can you clarify what you mean by “tracing the story of Ethel Quin”
Where & when was she born?
Presumably divorced Glenister as he only died 1990. They had a child born 1947 who appears to have remained in England as there is a marriage in 1965.
Geoffrey G Baird appears to have been b 1929 whereas Victor Glenister was b 1920
You may want to change your subject header. You are looking for Ethel Baird nee Quin.
