I know almost all genealogy sites have a searchable SSDI. One time I searched one looking up my grandmother, and it came up and gave me her parents last names as well as the birth date, death date, SS# etc. Now I can't find this site again.... All of them that I try searching on, doesn't list the last name of the person parents. Can anybody tell me where I found this so I can use it again? Thanks, Sandi
