the2herrons on Family Tree Circles

My nephew and I are trying to trace the Bannister side of our family but have run into a brick wall at John Bannister, born in 1833. Below is as far as we have been able to trace. Hopefully you might have some more information or be able to point me in the right directions.

Thanks,

Susan (Sawtelle) Herron
