This website contains a brief summary of our one name study of the Swinfen family. The name is relatively rare, and while we have not (yet!) joined up all the branches of the family, it is reasonable to assume that there is just one tree involved. There are significant branches of the family in Leicestershire, Birmingham and south Staffordshire and London, with a smattering of other individuals across the rest of England. Until recent years there are few instances of the name outside England, though members of the family are now known in Ireland, Germany, America and a couple of other countries.
