Today I was doing some research of my family on Google, and after a few search's I remember the SSDI.  I cant believe that I forgot this useful tool.  I use the one on GenealogyBank.  After a few misses I believe that I found a few good ones tonight.  I wonder how many other people have forgotten to use online tools once in a while.  At this time I dont have the money to subscribe to the big websites (ancestry.com), but I have a few library cards around the states that I can use.
