Richard WHITE is turning out to be equally as useless.
I suspect that this Catherine NELLES is either a possible daughter of James NELLES and Catherine STRATFORD (m. 18 Sep 1805 at St. Hilda's, South Shields according to the I.G.I. but the bishop transcript is missing) or Catherine got remarried. If she got remarried, I don't see why she would need her parents consent though so a daughter seems more likely.
James NELLES had 2 daughters which were born in Seaton Sluice, Northumberland , which comes under Earsdon parish, and Catherine STRATFORD had a younger sister Ann.
... there is an Ann STRATFORD and a James WHITE married in Earsdon By North Shields, Dec 1807 (Bishop Transcript is useless). So perhaps Richard WHITE is a brother of James and therefore this Catherine NELLES's uncle-in-law
