Cosbygp,
Yes, St Alban's was the " mother" church for the whole territory of the Parish of Earsdon. And Seaton Sluice and Hartley communities within that territory.
In early days St Albans was the only C of E church within terrotory. Then as populations grew and moved "chapels of ease" were established to save folks shoe leather. Eventually these chapels got their independence from the mother church.
I deliberately threw at you only C of E churches that were operating in the era of the birth of your target.
And that takes care of C of E business. However if the family were not C of E, then churches of other religious denominations were available both within and outside of the Parish bounds.
I notice a church dedicated to St Paul was in the Seaton Sluice, but in modern times.
And in about 1886 a C of E church, in Backworth was dedicated to John the Baptist. Backworth at the time lay within the Parish of Eardson, about mile and a half west of Eardson. But for folk from Seaton Sluice the journey to the Parish church in Earsdon village would have been shorter than hike to St John's Backworth !
