Why change the Search function just because you can? - Terrible!
I pay for Ancestry but my first-stop search choice was always FamilySearch for its far superior search function.
Example just recently an Ancestor from Kent with links to other Ancestry members were all at a dead-end after 1841 Census but I found him straight away in FamilySearch, moved to London by the 1851 Census so was able to track him to his death. I STILL cannot find that 1851 Census in Ancestry no matter how hard I try.
Tried the new FamilySearch function but now, don't even want to look at it, have even removed it from my Bookmarks as it's now just a waste of space
