Thanks both for your replies.
I have not explored those possibilities before regarding Phoebe marrying an Isaac Frondigoun so do not have the marriage certificate or divorce petition, also not heard or come across a Joseph Banham before.
If it helps Phoebe's parents were Samuel Thomas Hughes 1827-1895 and Diana Hughes 1830-1892, as a family in 1871 were living at 24, South Street, Queensborough, Sheppy, Kent, in 1881 they living in a travelling van at Canal Field, Milton in Gravesend, Kent.
Any help or info you can give would be great either to rule in or out it is the Phoebe I am looking for.
I have also never been able to trace her death so think it must of been under a different surname.
