Jones -Lewis - Chesterfield

[Gurslad]

Hi,
I'm looking for info on the following from Chesterfield:-
Ewart Frank Jones 1915-1979, was living at 27 Bevan Drive,Inkersall, Staverley, Chesterfield. A retired Railway Shunter.
Frank was born in the Forest of Dean Gloucestershire.
His wife was known as Peggy, but her real name was Martha Ann, according to the 1979 Electoral Roll. I searched Ancestry and I'm pretty sure her name was Martha Ann Lewis born 2 Jan 1917 in Chesterfield. That fits with the 2 known children David & Anne, Ancestry gives their mothers maiden name as Lewis. So hopefully I'm on the right track. A Martha Ann Jones died 1999 in Chesterfield.
Has anyone any info on Martha Ann Lewis or her family.
Jim
