the family you found in 1881 (info by pm) looks interesting. John's surname has been mistranscribed in 1871, so he didn't have show up when searching for John Perry.
1871 Pentre, Middle, Ystradyfodwg RG10/5384 folio 95 pg 10
Charles Perry head mar 36 mason b. ?
Louisa wife 37 b. Pembs, Narberth

Mary Ann dau 12 female servant b. Llanwonno
Henry son 8 b. Aberdare

1861 Oxford St, Mountain Ash, Llanwonno RG9/4048 folio 11 pg 16
Charles Perry head mar 25 b. Wiltshire

William son 6 b. Aberdare
Emily dau 4 b. Aberdare
Mary A dau 2 b. Aberdare
William Bresswell lodger unm 27 labourer b. Yorkshire

Slight problem being that the couple have a son called Henry, so why would John be John Henry?
