I am trying to trace my great grandfather George Swanson. All the documentation that i have (marriage cert, death cert etc) shows that he was born in Middlesex / London about 1854. His parents were Charles and Anne. I have located the family in the 1861 census but I am unable to locate my George in the BMD index's, even after searching the years surrounding 1854 and spelling variants of the surname, such as Swanston. Is there anyone who can help me resolve this "mystery"?
