FreeBMD
With the simple objective to make the GRO index free to researchers, FreeBMD is a bit of a legend amongst family historians and has spawned the sister sites FreeCEN and FreeREG. Don’t be fooled by its rather dated look, this site is easy to use and huge with over 245 million records that will help you order the right civil registration certificate. However, as the site grows it has become expensive to maintain, so they welcome any donations from users.
