Just been looking through all my old correspondence on The Budden's of Seldom and may have found something that may interest you. It looks like Joseph's second wife was Elizabeth COLLINS Boone who was the mother of Ezekial. She had one child from a previous marriage - Richard Boone.
You say your gg-grandmother Elizabeth married Joseph Budden from Carbonear. This Joseph may be the son of Stephen Budden born in Perry's Cove and Ann King. I have not found any other Joseph Budden's from that part of Conception Bay North. Stephen's father William of Sixpenny Handley, Dorset was my ggggrandfather.
I have been trying to find when Stephen died. I have the date of his wife's Ann death.
Hope this info is of help to you. Maybe we will make a connection and can share information.
