I occasionally receive these emails from ancestry; Thankfully they do not fill your inbox with a barrage of emails. Sometimes the hints are irrelevant, or I have already located the item they are pointing to, but sometimes they lead to something I had not yet gathered.
Below is the email notice I received today:
I had not searched for the Becker family in the 1915 NY census yet.
I have to admit it is pretty nice to have it handed to me this way.
