On this day, June 28, in 1914, Archduke Franz Ferdinand of Austria and his wife were assassinated in Sarajevo, sparking the events that led up to the beginning of World War I. After the United States entered the war in 1917, the Selective Service Act was passed to support the war effort and establish a series of drafts that would raise a national army. These drafts lead to the creation of 24,000,000 draft registration cards which contain valuable genealogical information that can help prove relationships and provide more insight into your ancestor’s physical description, birth date and location and more. The cards, more often than not, also contain your ancestor’s signature. The cards are searchable for FREE on FamilySearch.com at https://www.familysearch.org/search/collection/1968530 .
