Hello Averil. Birth and death dates of John Rennie have been put on Ancestry by a Palmer connection in USA and when I queried it I was told it was "guesswork". Death of John Palmer was the same. The year given for a marriage of Julia and John I haven't come across before so I have asked someone who has World Wide Ancestry to check it for me. It sounds a possible and Dunkerque was their home for sometime. The dates of Richard and alice Rennie I will check as I have the cert. for Agnes so I know she is their child. It is kind of you to take the time to help - Many thanks from Pat
