There is an obit. for Thomas Newell in the North Wales Chronicle (Bangor, Wales), Saturday, May 23, 1891
says he was an agent for Powis Castle for 50 yeras - The Herbert Family, of Clive of India. So maybe some records there. He was born c. 1805.
If this is your family there should be some records somewhere. Serrious digging will be required though.
