Hi, sorry for the delay in coming back to you.
The Ancestry tree is incorrect with regard to Stephen's parents (Clifford & Hilda) - my sister created that but the dates don't add up and afawk there are no connections to America.
Stephen had 2 brothers - Frank and Peter.
He was married to Vera Jablonsky (my mum's mum who has died) but they divorced and he subsequently married Elsie Davies in 1973.
@kloumann - I think you may have the correct Stephen/Mary E Rice as last night we found a photo of a gravestone. I can't upload for some reason, but it says
Mary Ellen Murray
The beloved wife of Stephen
Died 23rd March 1968(?)
Aged 83(?) years.
