I've got a statement i'm making
In the Northumberland area there are numerous David Cockburn records in Tynemouth, North Shields, Wallsend, Wooler, Berwick-upon-Tweed, and others.
That obviously needs a source but it isn't for a single database or record it is from the entire website. So this is my attempt to cite the search.
FindMyPast, search terms, name >David Davidson Cockburn, birth year > 1803 +-10 years, location > Northumberland radius >100 miles, (https://www.findmypast.com : 1 December 2020), 130 results.
FindMyPast. Indexed databases. https://www.findmypast.com : 2020.
I certainly don't want to list all of the databases that went into the search :)
