Original post implies that the name of the person is John Elwell. The wording if the newspaper clipping seems to confirm this.So it looks as if she might have been his sister. John Elwell being an alias. I haven't found a marriage yet for Louisa Bright to a Mr Roberts.
Haven't seen anything to prove that he is the John Elwell born Kingswinford though and not one of the other ones born around the same time.
