Hi,
I used
http://www.bmdregisters.co.uk when it first came out as I wanted to have an original copy of an entry for and ancestor from my husband's line, who family were members of the High Pavement Chapel, in Nottingham.
I had visited Nottingham University's Manuscript Libraby a couple of years ago, and gone through of the original registers, copying out all the entries for the surname Richards. To my surprise (having looked on the LDS site) the particular entry I needed had been changed, and the name of the father changed from William to John.
This piece of information enabled me to contine plotting the family line. On
www.familysearch.org the father's name is William, and anybody trying to research that family using their records would have got no further - no marriages, children, anything that matched.
Anyway, because I wanted an original image of the Hig Pavement Chapel entry I paid for £10 worth of credits to get this. The whole of the £10 was eaten up getting this image, and guess what, it wasn't the same as the one in the original register!
So as well as feeling peeved that I'd paid a lot of money, I had the wrong information - AND so will everyone else!
When I was at the WDYTYA show in London I mentioned this to someone from The National Archives, and asked if they'd used the Dr.William's Library records, and the reply (the gentleman didn't know for sure) was that they had probably done a deal with LDS - which has the wrong details!!!!
Thank goddnes I had gone in person to see the original register, otherwise my research would have come to a full stop. I know that William's father definitely was John, as I've since done a lot more research, and wills, etc all confirm this. Some, however, abroad or far away won't, however, be able to do this, sadly.
