Margaret Williams Murder Stone

Margaret Williams, a 26-year-old domestic servant, was found dead in the marshes below St Catwg's churchyard, pregnant and showing signs of violence. Local suspicion fell on the son of the farmer she worked for, but no charges were ever brought. The stone was commissioned a year later by local industrialist George Tennant, with the inscription composed by Elijah Waring. SOURCE CHECK: the 'Historic England listing 300082089' cited below does not exist (dead link) - and Historic England has no remit in Wales in any case, so this stone would fall under Cadw/Cof Cymru, not Historic England; the citation looks like a slip rather than a real record. Haven't yet been able to find an actual Cadw listing for this stone - worth checking Cof Cymru directly. Also worth resolving: one further source found in a wider search (a local Facebook post, unverified) claims a suspect was formally charged with the murder and acquitted for lack of evidence, which would contradict the 'no charges were ever brought' line above. Flagging as an open question rather than changing anything on the strength of a single social-media claim. OPEN QUESTION RESOLVED: the Neath Antiquarian Society's own article on the stone (by Martyn Griffiths, now read in full - it timed out on an earlier pass) clarifies the earlier Facebook claim of a charge-and-acquittal: the farmer's son was arrested and an inquest opened in Neath, the jury was kept overnight, but it was 'found that there was not enough evidence to charge the young man and he was released' - an inquest and arrest, but no formal criminal charge and no trial. This is consistent with (and more precise than) the 'no charges were ever brought' line above, so no change needed there, but worth having the fuller picture on record. The article also names the verse's author, Elijah Waring (1788-1857), and confirms local industrialist George Tennant (then building the Tennant Canal, opened 1824) paid for the stone. No Cadw/Cof Cymru listing for the stone was found in a further search - it does not appear to be a designated structure under either heritage body, which fits with the earlier 'Historic England 300082089' reference being simply wrong rather than a typo for a real Welsh listing.
