Hello, and am only passing through, so only planning on visiting the graveyard at the parish church, which I believe is called St Mary's, Therfield. I have a subscription to ancestry.co.uk, and don't plan on visiting any records office. This is a few days I have free while my wife and children are away, so I plan only a quick primary visit, and if I find anything interesting, I can plan a longer visit later. I am also planning the same thing in Bedfordshire and Leicestershire, with just a day or so in each county.
