IrishOrigins, and, indeed, Origins.net, will close down in the next few days.
This won't come as any great surprise. Origins was bought by DH Thomson Family History, the parent of FindMyPast, a year ago and the site has been carrying a banner announcing its closure for most of the past few months. In the meantime, all the Origins records have migrated to the FindMyPast database.
Origins was the first company to set up a pay-as you-go model for online family history records and had a particularly strong line-up of Irish records at a time when there was very little else available for those researching ancestors from Ireland.
So now the time has come to say adieu to Origins.net.
UPDATE, 16 March: Origins closed today. The landing page of the origins website directs all visitors to FindMypast.
