Edward (butcher) and Elizabeth Wright had the following children baptised at Ruabon:
27 July 1823 William. Abode - Newbridge
17 Nov 1824 John. Abode - Newbridge
6 July 1826 Joseph. Abode - Cefnmawr
20 Jan 1828 Mary . Abode Cefnmawr
Newbridge and Cefnmawr were part of the newly formed (1844) parish of Rhosymedre.
I'm wondering if the 'born Rhos' for Mary on one or two of the censuses might mean Rhosymedre rather than Rhosllanerchrugog. Although the latter is the one that is usuallly referrred to locally as Rhos. I've not heard of Rhosymedre called just Rhos.
I don't, at the moment, see a marriage for Edward and Elizabeth in Ruabon. Maybe neither of them were of Ruabon but moved in later.
There's a family in Cefnmawr in 1851 ( HO107/2503/176/49 )which is tempting but I'm not convinced it's them - Edward is a warp man, which doesn't fit with being a butcher earlier in life and thes don't quite fit. None of the children appear in the Anglican Church records of either Ruabon or Rhosymedre.
Throwing this in the pot for consideration -
Baptism, Ruabon 12 Sept 1830 - ElizabethDavies/Wright, illegitimate daughter of Edward Wright and Sarah Davies, both servants. Edward of Plasbenion and Sarah of Pontadam.
I'm hoping to get sight of the Rhosllanerchrugog records later this week.
