Birtle - this is why I'm querying the Haslington baptism.
I think there's evidence that they are two distinct individuals:-
Re JF in Haslington:- John Farr, tailor = Ellen Key, Barthomley 25 Jan 1780.
Their son John bur 5 Oct 1798 age 1 week (father John is described as a tailor of Winte[r]ley - regarding which, see Genuki under Haslington). Various other children bp 1788-1797 Haslington/Barthomley but not further investigated. John and Ellen not yet killed off!
Re a (different) JF in Manchester:- will of John Farr, late of Manchester, linen draper 1813 [cf Index of wills].
JF bur 16 July 1813 Cheetham St Marks chapelry, age 54 [ie b 1759ish], abode Market St, Manchester. That fits JF s of Thos bp July 1759 Manchester.
As a fustian cutter of the town of Manchester he may have married Alice Holdcroft 1784 Manchester St Denys... (they had children up to 1803); Alice bur Cheetham St Mark 1805 age 40.
I'm not saying that either fits AC's bill, but they do demonstrate the existence of two distinct guys named John Farr, either bp 1759 Haslington or 1759 Manchester.
