This was quite a mystery to me and took some time to unravel. Harriet Humphries was born as Harriet Merry. Her mother, Frances Merry, married the widowed John Molesworthin 1852. On the census forms all children, including Hohn Molesworth's children from his first marriage and Harriet are listed as Molesworth. When Harriet Merry, marries William Humphries she lists her father as Henry Merry, a tailor and uses her birth name of Merry. I have not been able to find any information on Henry Merry nor the possible marriage with with Frances Merry. I noticed that John Molesworth had signed the marriage banns as witness and that Frances Martha Humphries was listed as a grand daughter on Frances and John Molesworth's census forms. The other children of Harriet and William live with William and Harriet just not the first born, Frances Martha Humpries (my great grandmother). I suppose I shall never find an answer to that riddle.Quick question - how are the Molesworths the grandparents?
