Elizabeth Wetherholt Jackson (Brake) - Who really were Elizabeth's parents?

If the Findagrave memorials are correct, she would be born to a ten year old mother and married at age 27.

This seems impossible. But where the error is, is not clear. Her supposed mother has a recorded baptism date of 1762 in Berks County PA, so that is likely not in error. Her supposed father would have fathered her at age 18, and that also seems unlikely.

So, I wonder if the identification of her birth family in FindAGrave is entirely wrong. There are plenty of other Wetherholds to choose from which do not have these obvious problems. The alternative is that the family is correct and her date of birth was at least 8 years later.
