I had a play with free bmd site, found parents names
Bertie T Leach married Bessie C.K. Newton , St Thomas regn area 1928.
children Frederick W born 1929, Stanley B.T. 1930,
Richard 1931, Margaret 1934.
then looked on find my past and its still St Thomas regn, with Bessies name given as Bessie C McGuinness. with one other person and 2 closed, so one of the children may not have survived. But using Bertie and Bessie, went back to freebmd and found Bertie T registered Crediton 1895, so he should be on 1901 and 1911 census, and Bessie Cornelia C registered 1906 St Thomas, so she should be on 1911
If you pop in the heritage centre and use the computer there, you can get the address etc on find my past for free.
Hope this has helped.
