Hi Peter,
I have no info on Thomas Jnr whatever, I can't find his birth in Cheshire and no definite siblings and I have found no middle name.
I have found a Thomas Powell born in Liverpool in 1733 which would be about right and his father was Samuel, EUREKA I thought, Thomas's first son was Samuel, then I found Thomas's wifes father was Samuel too, so no evidence really.
What is interesting is my cousin came across a piece of paper dated 1880 which reads "Thomas Powell my great-grandfather took this property from the common". Just makes me wonder if he had come from somewhere else and made a home for himself in the Wirral. Any ideas Peter?
Regards
Sue
