It looks like the first sign of Thomas was in 1644 in Connecticut so he might not make the PGM cutoff.
There is no source for his origins in England, just a suggestion he was related to the Catlins of Kent. He recently had an unsourced mother attached. I've detached her and the unproven father.
Would a leader kindly add PPP for Thomas and his second wife Mary (Unknown) Elmer. She is in a proposed merge and her Unknown needs to be conserved.
