"Note by another author: It seems that the recurrence of the name William may be causing some generational confusion here. Mary Horner, mentioned below, married Joseph Fletcher on 14 November 1822, at the school Kingswood. She could hardly have been less than 16 at the time, meaning she was born no later than 1806, at which time, if this date of birth is correct, Horner would have been only 20. And Mary's sister, Sarah Jane, was baptised on 5 June 1803, at which time Horner would have been a few days short of 17. Whilst none of these things is impossible, it seems more likely that Mary and Sarah Jane were this William George Horner's younger sisters, daughters of William Horner senior."
