Dawn,
Many thanks. It's over a year since I looked at FindMyPast's Yorks Marriage Transcripts. They claimed in a Press Release to have covered Sheffield, but when I came to compare their results with my own "Marriage Mining", I found that they had transcribed very few indeed. Perhaps things have improved. Nevertheless, I am at fault for not looking and thank you again for rescuing me.
Carol,
Many thanks for the transcript, presumably from the same source. Curiously, perhaps, what struck me most about the witnesses was the Butler who gave only initials (plural). It so happens that the only two people in that family who properly had more than one forename had initials S M R and F E, the latter actually being a Butter (Reuben's aunt Gertrude Butler married Francis Edward Butter, in a move cunningly designed to test transcripts

. Even aunt by marriage Sarah Janet Butler did not properly have the Jane or Janet forename - she was registered as plain Sarah Teather, Jane being a later addition.
I apologise for having put the same request under Yorkshire, but you will understand my doubt about whether it would be fulfilled by Derbyshire Roots Chat. Again, many thanks.
Keith
