Frances, as you will see from the certificate, was a widow, although, as she was born in 1818, she was only 22 when she married Charles, so Tapscott was her previous married name and her maiden name is shown in the column for father's name. Unfortunately, it looks as though ink was in short supply that day, hence the poor quality of the print out. Either that or that's where I get my bad handwriting from.
I can see the man was a 'yeoman' and that his first name was John and that his surname ended in 'eland' and I think the first letter is a 'G' as it corresponds pretty closely to the 'G' in 'Gardener' which is down as John's occupation at that time.
I have trawled through endless lists of Devon names in an attempt to find something close to what is on this certificate, to no avail and I have not found any trace of Frances's first marriage, although, as it presumably took place before the coverage of the free BMD, it would be harder to trace anyway.
So, there we are, a brick wall. Not important in the grand scheme of things but a mystery I really wanted to solve in the hope that it would shed some light on the next step, which will perhaps be a subject for a future post...
