My Grandparents got married at the age of 15 & 18. They were married till death and had 5 children. Of course, times were different then.
My grandparents met when he was 26 and she was 16. He was a decorated soldier coming back from WWII. They were together 60 years until his death and had 8 kids. These days he’d be a life long sex offender and most of my family would never have even been born.
