Yesterday I was able to see a photocopy reproducing a typescript version of notes on Llanrhaeadr-yng-Nghinmeirch MIs made a century or so ago by W M Myddelton (the man who edited the published Chirk Castle Accounts). The original is at the library of the Society of Genealogists in London.
I do not have total confidence in the accuracy of this typescript, made by E W Topham Steele, because (a) I know Myddelton's hand can be difficult to read and (b) some extracts do look suspect. However, parts of the notes seem relevant for present purposes and worth reporting here.
Evidence suggesting that Edward Williams, vicar from 1822 to "1843" (see addition to Reply 3 in this thread), was resident and ministering in person to his parishioners is the fact that the MIs show that on his premature death in 1842 aged only 46, he was buried there rather than anywhere else -- as were other members of his family later in the century (his widow is said to have gone off to South Africa to become a missionary). Furthermore, the MI notes include a memorial dated 1836 to "Jane Hughes . . . for 15 years the faithful & respected Housekeeper of Rev Mr Edw Williams, Vicar of this par. Died at the Vicarage."
The extracts also record MIs to Robert Lloyd Anwyl Roberts (the man I labelled the Great Nephew in Reply 11) and his immediate family, grouped together in such a way as to suggest that they may all have been on a single monument:
1. Rev Robert Lloyd Anwyl Roberts, late of Bryn Morwydd & Rect of Llanganhafal, ob 6 Mch 1876, aet 77
2. Ellen Roberts 2nd d of Rev R Prichard of Dinam Anglesey & relict of above Rev R Ll A, ob 16 Jun 1882, aet 82
3. John Augustus Roberts 3rd s of above, ob 28 Jan 1851, aet 18
4. Wm Vincent Roberts 4th s of same, ob 17 Apl 1876, aet 40
5. Richd Anwyl Roberts 2nd s of above, ob 21 Feb 1885, aet 55
6. Anne Adelaide Roberts only surv d of above, ob 25 Jun 1906, [aet] 63
For the sake of completeness I am also adding here some additional references to the Roberts family. The CFHS transcript of Llanrhaeadr PR records the baptism of the Great Nephew on 9 April 1798 (with the forenames Lloyd and Anwyl apparently reversed), son of the Revd Robert Roberts, vicar of this parish, and Margaret his wife. Back on 13 December 1775 the same source records the burial of the Uncle: Robert Roberts, late vicar OTP.
Finally, Foster's Alumni Oxonienses, cited about the Nephew in Reply 11, also has entries for the Great Nephew and the Uncle:
ROBERTS, Robert Lloyd Anwyl, s. Robert, of Llanrhaiadr, co. Denbigh, cler. JESUS COLL, matric. 28 May, 1816, aged 18; B.A. 1820, M.A. 1825.
and
ROBERTS, Robert, son of Robert, of Trawsfynydd, pleb. JESUS COLL, matric. 23 March, 1737-8, aged 18; B.A. 1741, M.A. 1744.
