From the Sheboygan (Wis.) Press-Telegram of Apr. 23, 1923:
Washington—Prove your birth by the United States Weather Bureau: it can and has been done.
Recently, they say, a man was called upon to prove the date of his birth. Family tradition pointed to it as being in a year "when New Year's Day was very, very cold—the lowest temperature on record" for that district.
The bureau looked up its records for the vicinity and was able to substantiate the man's claim to being born in 1864, when the new year was ushered in with temperatures from 10 to 18 degrees below zero, unusual for his state.
