State of Illinois
Age of marriage:
- 1819-1974: Males 21 and females 18. With parental consent, 17 for males and 14 for females. Changed to 18 for males and 16 for females in 1905.
- 1974 to date: 18 and over for both sexes, 16 with parental consent, 15 with a court order.
I transcribe marriage licenses for my local county genealogical society in Illinois and have seen numerous licenses where, even though the bride was under 18, her parents never actually signed the license giving permission. This may be what happened in the cases you refer to.
On one license, the clerk wrote the bride was "Over 18" and actually put the quotation marks around the statement. There was no permission from the parent, which intrigued me as the same clerk had never used this prior. I did some digging the bride was in fact under 18 at the time, and within 5 months gave birth to a child according to the Federal Census of the time. I envision the bride swearing to be over 18 while standing on a piece of paper marked "18". In that way, she wasn't lying but wasn't completely truthful either!
I hope this helps. I have seen the same situation for some of my relatives going to Missouri from Illinois for the day to get married. Older family members related it had to do with waiting periods of the time between getting a license and getting married.
