The following is from MyHeritage:
On the eve of the 1950 U.S Census release, I’m excited to tell you that not only will the census records be available to explore on MyHeritage very soon and for free, they also just released a free tool that will help a great deal as you prepare to dive in: the Census Helper™.
The Census Helper™ scans your tree and automatically compiles a list of individuals appearing in it who are very likely to be found in the 1950 U.S. census, along with relevant details. Armed with this list, you’ll know exactly which family members to search for in the newly released records, and your research will be much more focused. You’ll also be able to research those individuals in the census records with the click of a button.
I highly recommend to anyone who doesn’t have a tree on MyHeritage to upload it as a GEDCOM and use this tool for free, so they can get a head start on their research. You can do so via this landing page.
I personally tried it out, and got 1,634 folks that I should look for starting on April 1 (midnight tonight). Another 1,113 were also available, but with lower confidence. This is based on my tree posted at MyHeritage.com. The entries start with my closest relatives (me in this case – although I won’t be there, as I was born 13 days too late), and are compiled in logical order going back and out in my tree. Very, very cool!
