West Yorkshire Archive Service
http://www.archives.wyjs.org.uk/They have an online catalogue which I suspect is incomplete (I have viewed documents at Calderdale that are not listed in this catalogue at the moment).
However, useful resource even for Briercliffe interests if you are prepared to travel across the border to view the stuff. There are a few documents for Briercliffe, Burnley etc. I didn't look at surnames, only one or two villages of interest to me. I have started my list for my next visit to Calderdale - who knows when that will be! I have found one or two references that may connect with the information in the will I received from the Borthwick Institute this week (mentioned on that topic).
I want to go now!!!
