Some excellent materials there - one down side though, is that as with the FamilySearch offering for civil marriage indexes, there is no way to search for matching partners on the search screen - BUT - you CAN click to see others on the page on a search return. I have just tried to find my 2xgt gramps Cochrane Watton, and in seeing who else is on the page, four women are returned, one of whom is Elizabeth Holmes, who was indeed his wife. In other words, this has just trumped FamilySearch.
I knew the Catholic records were coming, but had no idea about the civil registration records! There's no details yet as to whether the civil records collection is more comprehesive than FamilySearch after Partition in 1921 - no doubt Ancestry will have a press release out soon!
