Thanks for the replies, they support the evidence that I have
I have a copy of the marriage certificate for William and Alice Hood
Williams father is given as John Walford, in all the relevant censuses his father is given as John Walford
I cannot find a John Westbrook Walford in any of the censuses, I don't think he would drop the Westbrook from his name
My belief is tht someone has linked John Westbrook Walford to William without any supporting evidence and others have copied this data
Thanks
Steve
