Probably irrelevant,but while I was looking for a Richard "X" as father I came across the following which supports the fact that a "plain" David Meredith(not David Meredith Richards) was at Ffosybleiddiad(the 1851 census has him born at Llanychaearn approx. 1784 which probably fits with him being the son of Thomas Meredith(1754-1832,will at NLW?).I was slightly excited because there is also a Richard Meredith(possibly 1725-1805) who might have fitted the bill,but his will makes no mention of a son James(though there is a John) and they seem to use "surname naming".I can't find a connection by marriage with a Richards family either.
