Just thought I would post a heads up about a new service from GRO
www.gro.gov.uk/gro/content/certificates/login.asp
You can buy instant access to images of registers of births from 1837-1922 and deaths from 1837-1887 for £2.50 each. Huge discount on ordering even a pdf copy
I am going to order a few today. Often death certificates hold the most interesting research on an ancestor. I think this is quite a game changer for genealogy research as the cost can be prohibitive.
