Married 8/29/88
First child’s birthday 4/20/89
I suspect you can do the math on that. They eloped for a reason. She was pregnant. And you’ll need some evidence if you wish to speculate that Track was a premature birth.
Your "math" is rather speculative, and proves absolutely nothing as far as the elopement.
The child could easily have been born a few weeks premature, so assuming the most negative explanation is not particularly compelling.
The dates are facts, friend.
That they eloped because she knew she was pregnant is opinion. Based on the math.
Bring your evidence that Track was born at 37 and a half weeks.
