Thanks for your helpful response, I was able to find you and your tree.
BUT we don't show as DNA matches.
Our common ancestor is I think 10 generations back. DNA cannot lie but nevertheless I'm not sure if Ancestry's DNA tools are tuned highly enough to match us!
My paper trail for the Powells is in my opinion 100% correct.
I presume you have seen the attached image before? From The History of Brecknockshire by Theophilus Jones
My David Powell b 1745 (Elinor's brother) only had one child (David Walter Powell) which has made things simpler, less to confuse!
He had 4 daughters (2 were born after this pedigree was composed) and after his death my connection to Devynock ends, his widow and the daughters disperse through marriage to Cardiff, Swansea and Monmouthshire.
DNA, confusing stuff!
