Hello Christine
Just to cornfirm I have the details of a GRO death cert for Margaret Thompson 10th September 1839 at Folly age 36 wife of John Thompson, Tailor. Informant John Thompson present at death. So, if this is the correct death cert it means she was born in 1803, casting doubt on the 1815 marriage, I'm beginning to think someone has made a transcription error somewhere, as the dates for all the children seem to fit in well with the 1815 marriage. What do you think?
