The SS-5 has a lot of useful information, including where the individual was employed, their address, and names of boh parents, but I ordered it primarily because it is supposed to contain as detailed a place of birth as the applicant knew. I am trying to figure out the town in Russia he was born in. Every other document just says ‘Russia’. He’s one of my Dudelsack ancestors, though he would have had his name changed at age 4.
Unfortunately, by 1936 when Social Security began and he applied, both of his parents were dead, and it turns out he didn’t know the town, so I am still in the dark.
