Judy, there is no "complete list of all of those who served". Here is some info you might be able to use. Some are resources I have used researching my own family, others are those I have only read about, or found online. Please verify all to your own satisfaction, or seek professional assistance.
Note that DD-214 is incorrect terminology. That form was not used as proof of separation until after WWII.
I searched for him in the Archives enlistment database. Listed there is: Henry L. Lairson Serial number 18013976 Residence: Nueces County, TX Date of Enlistement: November 19, 1940
If he ever applied for benefits, you can contact the Dept of Veterans Affairs to see if they have info that could help you. The national number is 1-800-827-1000. Also, you may have a "nearest DVA regional office" in your area. The VA web address, with other info, plus a list of facilities, is http://www.va.govhttp://www.va.gov
Other possible sources include: 1.Veteran's organizations (e.g. American Legion) of which he may have been a member at his place of residence after the war. 2. State Historical Records Office (of state where vet resided at time of entry into service). Ask them to check service record cards, bonus records, and Reports of Separation that the state may maintain. Internet listing of state historical record coordinators: http://www.archives.gov/nhprc/about/state-coordinators-boards.htmlhttp://www.archives.gov/nhprc/about/state-coordinators-boards.html 3. U.S. Civil Service Commission, Bureau of Retirement and Insurance (if retired from federal employment) 4. Any employer to whom a record of military service was furnished. 5. State Adjutants General (if any service was performed in the National Guard). 6. Social Security Administration (if a claim for old age, survivor's, or disability insurance benefits has been filed and the service involved was from 7 Sept 39 to the present). 7. Railroad Retirement Board (if a claim for railroad retirement or survivor's benefits was filed). 8. Hometown newspaper archives which might have stories about his service or homecoming.
