Ancestry.com has placed online the SSACI Social Security Application and claims Index 1936-2007. Unlike the old SSID (Death index) this new index includes any claim made to Social Security such as : name change due to marriage, name of parents,name at application for SSAN, name at death etc.. This is proving to be an excellent source for maiden names,parents names DoB, DoD etc. Be aware however that not everyone will appear only those who made a claim or application of submitted a name change etc will show. Another new valuable tool in your genealogical research. Don't have an Ancestry subscription? Go to your local library most now have a Library subscription you can use for free.
