World War II Begins: Tracing Your Family Through Draft Cards and Enlistment Records

World War II Begins: Poland, 1939, and a kitchen table in Ohio

Germany invaded Poland on September 1, 1939. Britain and France declared war two days later. The conflict eventually pulled in most of the world and reshaped where families lived, worked, and died. American entry came in December 1941.

Ask yourself what your grandparents were doing in the fall of 1939. Most of us answer that with a shrug and a story somebody told at a funeral. The war years scattered American families across the country for work, moved daughters into plants that had never hired women, and left a paper trail genealogists still underuse. Draft registration is the best of that trail: a snapshot of a man in a room on a specific day, telling a clerk where he lives and who signs his paycheck.

World War II Begins: The Old Man’s Draft and what is actually on the card

The Fourth Registration of April 1942 is the one I keep coming back to. Genealogists call it the Old Man’s Draft. It covered men born between 1877 and 1897, roughly 45 to 65 years old. Nobody was sending a 63-year-old machinist to Normandy. The registration worked as a headcount of experienced labor, which is exactly why the cards are so good for us.

Look at what a card holds. Name and current address. Age, date and place of birth. The employer’s name and address, or the place of business if he worked for himself. And a field I love: the name and address of a person who will always know the registrant’s address. On the reverse, a physical description taken down by the registrar. Height. Weight. Complexion. Eye and hair color. Identifying marks such as scars.

A hypothetical example, and this man is invented for illustration. Say your great-grandfather is Stanley Wozniak, born 1895 in Buffalo, New York. His 1942 card gives an address on Sycamore Street, an employer listed as a machine shop on the east side, five foot seven, 168 pounds, scar over the left eye. The person who will always know his address is a neighbor two doors down with a different surname. That neighbor is not decoration. He may be a brother-in-law, or the man who came over on the same ship. I have cracked more than one brick wall by chasing the person in that field instead of the person on the card.

Now, the question I get every time I teach this: Didn’t those records burn?

No. The 1973 fire at the National Personnel Records Center in St. Louis, Missouri destroyed an enormous share of United States Army personnel files, the service records of people who actually served. WWII draft registration cards are a different animal. They were created by the Selective Service System, a civilian agency, as part of a nationwide registration of the general population, and they were not stored with the Army files that burned. The Fourth Registration came through untouched. If a card is missing today, 1973 is not the reason.

World War II Begins: Pinning an ancestor down to a month

Here is where it gets good. Take the draft card and set it beside WWII enlistment records for the same family.

Most of us research in years. He was in Buffalo in 1940 and Detroit by 1945, and the middle is fog. These records let you work in months. A card dated April 1942 puts a man at a street address with a named employer that week. An enlistment record for his son, dated a few months later, tells you the household changed. The fog gets edges.

Occupation is the hinge. If the 1942 card says machine shop and the family story says he “worked for the railroad his whole life,” one of those needs a second look. Probably the story. Stories compress. Paper does not.

World War II Begins: We used to think 45 was old

Something worth sitting with. The men who filled out those April 1942 cards were considered old. Forty-five and past the point of usefulness in uniform. My grandfather’s generation talked about a man of 60 the way we now talk about a man of 85.

Baby Boomers did most of the shifting on that. Sixty-five stopped meaning a porch and a pension and started meaning a second career and a DNA kit under the Christmas tree. Nice to notice, but it carries a warning. The people we still think of as sharp and available to answer questions are the same people whose parents filled out those cards. That window is not open forever.

World War II Begins: Call one of them today

Not this weekend. Today. Pick the oldest person in the family who still answers the phone, and ask about work.

• What did you do for a living, and who did you work for by name?
• What did the building smell like when you walked in?
• What did a paycheck buy that week?
• Were you ever laid off, and what did the family do about it?
• Who got you the job?
• Did anyone in the house work a defense plant during the war?

Occupation detail is what makes an interview and a draft card corroborate each other. When Aunt Doris tells you her father cursed the foreman at a plant on the east side, and a 1942 card lists an east side employer, you have two independent sources agreeing. That is evidence. A story alone is a lead.

And do this before Friday. Pull one relative’s war-era paperwork, just one, and read the address, the employer, and the name of the person who vouched for him. Write down what surprises you.

The clerk who filled out that card in April 1942 had no idea he was writing to you. He was doing paperwork on a Tuesday. Eighty-four years later it is the only place on earth where your great-grandfather’s scar is written down.
