Hello Steph,
I'm just as confused as you are! I thought it was going well - Flo marries Peter/Paul, has a son Paul Herbert, Peter/Paul dies and Flo remarries to Edmund. The children then take his name CREESE on the 1871 census. But then the marriage appears in 1877 to Mary Ann F ANDREWS. This completely threw me, because his wife is still called Florence Jane in later censuses. I wonder if she is 'Mary Ann Florence Jane'. And did she ever marry Peter/Paul?
Found this couple in 1881
