I’ll correct myself... Does the young wife look as young as 20 years old who is in the picture with 3 children? (If it is Carolyn Jessop, then she could have had the first child at 18 yrs old, the second child at 19 yrs old and the third child at 20 yrs old)
Young is a common FLDS surname.
The husband in both photos is Merril Jessop. He was married to Carolyn Jessop. She is the one pictured, not someone named Carolyn Young.
