You won’t always find a neat and tidy birth certificate tucked into history. But don’t worry, you can still estimate a birth year using clues from other records!
Here’s how to play detective:

• Census Records often list age. (Just remember, people fibbed or guessed—sometimes wildly.)
• Marriage Records might list age at marriage. Add or subtract accordingly.
• Death Certificates sometimes list birthdates—or at least an age at death.
• Military Draft Cards (especially WWI and WWII) usually have exact birthdates!
• Gravestones sometimes offer exact birth dates… or the mysterious “aged 72 years, 5 months, 3 days” inscriptions. Bring a calculator!

💡 Quick Tip: Always double-check ages across multiple documents. If Uncle Joe aged 10 years between censuses taken 5 years apart, you’re not the only one confused.
