Margaret Marven (195) was born in 1943 in Chelmsford, Essex.
I believe that she married Geoffrey George B Rawlinson (591) (1943 - 1985) in Braintree, Essex in 1971
I believe that they had two children:
Susan Valerie Rawlinson born in Maldon. Essex in 1972
Mark Ann Rawlinson born in Chelmsford, Essex in 1975
