I was introduced to one of the neatest record sets at RootsTech 2017.
I have known Michael Benson for quite awhile. He lived not far from me, and was one of the microfilmers over areas east of the Mississippi River.
Even with 30,000 people to wade through, we always manage to find each other.
Just as we were saying our goodbyes, he asked me what classes I had taught at RootsTech. I told him that one of the classes was "Substitutes for Vital Records". He then asked me if I had ever seen the Old Age Assistance Tax images.
My interest was piqued, and I asked him what they were. Apparently, they were set in place just before Social Security began.
And, he had just finished filming a set in Iowa.
Look at the information on these cards! Each one has space for:
1. The full name of the applicant.
2. The date and place of birth.
3. The parents' name, including the mother's maiden name.
Oh, this is good.
Here is the bread crumb trail on how to find them.
Go to the FamilySearch Wiki and look under the state you're researching. Pay close attention to the taxation links.
Notice that #2 references Old Age Assistance Records, 1934-1936. There is a clickable link at the end of that line.
This is the landing page.
Here, you'll see a camera at the end of each line. There are four collections, all alphabetized.
And, there you go! Many, if not most of these individuals were born in the late 1800's -- before most states began keeping vital records.
So, check the FamilySearch Wiki to see if there are collections available for the states you are researching.
