Prelli,
Was trying a different track to find "Where born". Unsuccessful, but in case you have not already found -
GRO Birth Registrations-
Sarah Pemberton, Wrexham, Mar Qtr 1859, Wrexham, 11b 305
Sarah Pemberton, Wrexham, Jun Qtr, 1860, Wrexham11b 336
Both with the mother's maiden name Hughes
(Couldn't find an Edward with mother's name Hughes),
FindMyPast has the marriage certificate of a James Pemberton to a Hannah Hughes, Wrexham Reg'n district, 29 Aug 1857. James' father is George -but cannot find a baptism that fits.
If not relevant, please ignore.
