I think it is extremely unlikely that any family member will see this post.
This is a possible marriage for Leslie
Marriages September quarter 1961
Kathleen B Kelly N.Walsham 4b 1693
Leslie Page N.Walsham 4b 1693
This could be Kathleen's death
GRO 1st quarter 2016 in Norfolk
Kathleen Betty Page birth year 1924
and this could be her probate record
Kathleen Betty Page probate 05 October 2016
4943114 (probate number)
died 15 February 2016 Grant and will Newcastle Upon Tyne
so that would give 2 wills to look for named children.
