Just to mention, I had a read of the Will of one of James Martin Millhouse' daughter Mary Ann (Marian) written 1846, proved 1848. No mention whatsoever of any issue of her late brother Robert or of there being any surviving spouse of Robert or anyone with the surnames Tayler or Pool.
It does mention her siblings: Sarah, Abraham, George and Martin & Eleanor and various other family (Bush etc)
