FamilySearch has uploaded parish register images and indexes for Sussex 1530 – 1900, it’s hard to tell if every parish is online yet, but I recommend that you look at the Wiki as this has a coverage list. The press release from FamilySearch show that 110,000+ records have been indexed and there are 5,147 images available so don’t expect images for every parish, in fact I think this number of images would amount to just about one parish.
Taking into account the above this is still an important addition to the FamilySearch Parish register Collection and I have no doubt that the rest of the images will be going online in the near future. Those of you who read an earlier post may remember me reporting Diane Loosle from the Family History Library in Salt Lake saying that all the films and fiche stored in the famous granite vaults will have been digitised and online with 5 – 7 years, indexing will take 100 years at present rate of progress. If you would like to help with indexing I am sure they would be pleased to hear from you, link below.
