Re: Serching all Sangliers
Interesting, I have no knowledge of a Northumberland connection, however, the names are interesting since they are very popular within the family. My fathers name was William and Edward has been used as a second name a couple of times. Mary is also a name used in the family.
Sanglier is an incredibly unusual name - even in France in the Paris telephone directory there are only a tiny handful. There has always been this thing that if the Surname is Sanglier then there is a good possibility that it is a relative.
