RE: Digging up the past - playing detective (family history)

I plan to visit the Cambridgeshire Archives in Ely at some point - maybe over summer. That's where the genealogist managed to get to but then drew a blank. I need to read through their documentation on booking a visit and what I need before visiting as I think they aim to get all the records out ready for your arrival. I also need to practice how to read old writing!
