You looked for Isabella Libby. She is the stumbling block. We thought the name might be spelt Cowen - children are baptised as Cohen all seven of them between 1832 and 1848. James dies 1855 and Isabella Cohen marries (mother and daughter) and then a husband dies and she remarries but not sure if it is mother or daughter. I think I need to bite the bullet and buy about 5 certs to sort them. If I can sort Isabella I can then hopefully find her mother etc. A good nudge to try and get her sorted lol
