This is probably the nephew of Elias Jeremiah of Mynyddislwyn mentioned
in the latter's Will (see Notes to his entry). It also seems likely that
he is the subject of the Bond for �600 entered into by barristers
appointed as Executors for the Estate of "Elias Jeremiah late of the
Parish of Mynyddislwyn" in 1798 (Probate ref. LL 1798/78).
