Hello - and thanks for all the suggestions - I will now look at the adjacent areas' churches to see if they hold anything.
I have come across another confusing piece of information - the John Addison I am looking for was married to mary Reed, in, as far as I know, Earsdon. Ive come across an 'Addison John Cresswell' bn abt 1778 married to an Elizabeth Mary Reed. Is this just a massive coincidence?? As far as I know, Cresswell is in the same type of area as Woodhorn (?). there is a lot of info about them on rootsweb.
Any thoughts??
