We are looking for more information on Dadge pre 1766

We have a Elisabeth Dadge 1766 - 1846 who married a John Bertout 1765-1846

We have no idea who her parents were?

She died in Stroud Gloucestershire Though John Died in London, they married in London and both died the same year,

He died first in April so perhaps she moved back to stroud (family area) after his death?
