I've been tracking down my mother's family, who are Goverd from Somerset in UK. It is believed that the "d" on the end only dates from the 19th Century, and that before that it was Gover.
I would be interested in communicating with anyone researching Gover (or Goverd) to see if there is a connection.
I'm probably best contacted by e-mail to email@example.com
or by post to
PO Box 105
