Message 817 in this forum tells how to access an online book of Comstock Genealogy. Looking for “Bagsby” in that book just now, I found nothing. There were 33 entries for “Elmer”, not necessarily “Elmer Comstock”, which you might check out. If you have trouble searching that book, please let me know.
There is a Social Security Death Index at http://www.ancestry.com/search/rectype/vital/ssdi/main.htmhttp://www.ancestry.com/search/rectype/vital/ssdi/main.htm Looking for an Elmer Comstock with date of death in 1972, I found this: ELMER COMSTOCK SSN 280-14-2597 Residence:62248Hecker, Monroe, IL Born 30 Apr 1910Last Benefit: Died Nov 1972Issued:OH (Before 1951)
(The dates are only close, not exact. You can find the same information by looking for “Elmer Comstock” at www.familysearch.com ) Did your Elmer Comstock die in Illinois?
According to http://www.ancestry.com/search/rectype/vital/ssdi/faq.htm#whathttp://www.ancestry.com/search/rectype/vital/ssdi/faq.htm#what The Social Security Administration has a microfilmed copy of every individual's original Social Security application (known as the SS-5), as well as claims files. These documents contain additional information not available in the SSDI such as birth place, maiden name, and parents’’ names.
According to another part of the “Frequently Asked Questions” at that site, “The Social Security Administration makes copies of the original Social Security application form (the SS-5) available to third parties who request information on a deceased individual. A standard letter to the Social Security Administration is available with the search results on the Ancestry.com Social Security Death Index. To generate the letter simply click on the "write letter" link available with all search results in Ancestry's SSDI.”
So, you might write to the Social Security Administration.
http://www.rootsweb.com/~nebuffal/wwi/17.htmhttp://www.rootsweb.com/~nebuffal/wwi/17.htm says this: BRYAN W. COMSTOCK was the son of Elmer Comstock, of Gibbon, Neb. He was born March 29, 1898, at Gibbon. Private Comstock joined the service at Kearney, Neb., in July, 1917. He was trained at Camp Cody, N. M., with the 127th Infantry.
Bryan Comstock died in the 1918 flu epidemic. Was your Elmer Comstock the son of another Elmer Comstock? Do you have any additional information, such as places of birth, residency or death? Names of any relatives?
