The first draft was June 1917. That one was my uncle's. The second was June 1918. The third was September 1918. Over 24 million Americans registered for the draft. Considering the size of the United States at the time that was a healthy percentage of citizen records. The cards are preserved and searchable for FREE.
Included in the record are the date of birth, often a correctly spelled full name as the person was right in front of the registrar, place of residence, occupation, a relative's name (usually a parent or a spouse), a brief physical description, and, my favorite, their signature. Be still my heart! I don't know if any of you react as I do when I see ancestors' signature or writing. But I practically mist up. Okay, I DO mist up, realizing that they grasped that document, rested their hand on the paper, and wrote their name. It is magical.
Hopefully you found an ancestor or two after last week, ready to search in these detailed historical documents. HERE is the link to the free database on FamilySearch.

Below is my uncle's draft registration form. (The image reflects the way it was scanner by extractors).
