I'm hoping so as he is the only one I've found about the right time in Norfolk. The one married to Ada is definitely my great-grandfather. Ada was his first wife, and Mary, his second wife, was my great-grandmother. One problem is that some records say he's from Hull and others Norfolk - more say Norfolk so I'm going with that having exhausted the Hull option. I can't find him anywhere on the 1891 Census which might tie up the 1871 and 1881 Census with later details. His marriage to Mary was conducted by Rev George Claridge of Heigham, Norfolk so another Norfolk connection - and rather a strange one when he got married in Derbyshire.
