I have just come across your message regarding Thomas William Pallister born 1827 Lambeth Surrey.
I to have a Thomas William Pallister born 1827 in Lambeth Surrey who had a son Charles.
Charles Pallister born 1868 to Thomas William pallister and Ann Jane Bailey were my Grand Parents. I have no record or the Violet you mention and my mother knows nothing of her either.
The Thomas William Pallister I have was born 1827 in the workhouse soon after his father Thomas pallister arrived in what is now London. Where he came from is still a mystery although I suspect he came down from Yorkshire looking for work.
I note that your message was posted some time ago so you may no longer be looking for that link. if how ever you still are then please get back in touch as it would appear one of us has gone off track or there is a side to the family I am unaware of.
