Marmaduke makes an important point, when this type of thing happens it should be best practise for the site which is closing to say where all the information has gone, or is going to go to. Much the same thing has recently happened with Lincolnshire On line parish clerk, loads of information, site closing, then just zapped. Bad practise in my opinion.
There is a list on the Family History Online site with a 'traffic light' system showing which datasets have been transferred to FindMyPast and which have not.
www.familyhistoryonline.co.uk/database/index.shtml#LANThose with a green 'light' have been transferred, and those with a red one have not. Most of the red datasets are census indexes where FindMyPast already has its own index.
The amber lights are for datasets that have not been transferred, but which may appear on FindMyPast in due course; some of these are where societies are working with FindMyPast on the 1851 census indexing project; others are where no contract has been signed with FindMyPast, for whatever reason.
The datasets were always the property of the societies that created them while they were on FHO, therefore it is up to each society to decide what its future arrangements might be, so with the best will in the world FHO could not predict what they might be in each case. Nonetheless, FHO (or more accurately, Chad Hanna) went to the trouble of trying to provide as much infromation as possible.
