For his daughter Jillian, who has Down Syndrome, Daugherty penned a note as she prepared for her June wedding.

In it, Daugherty reflects on the challenges of raising his daughter, wanting the best for her and trying not to be overprotective.

“We all wish the same things for our children. Health, happiness and a keen ability to engage and enjoy the world are not only the province of typical kids. Their pursuit is every child’s birthright. I worried about your pursuit, Jillian."

In retrospect, he says he did not need to worry so much.

“Do you remember all the stuff they said you’d never do, Jills? You wouldn’t ride a two-wheeler or play sports. You wouldn’t go to college. You certainly wouldn’t get married. Now… look at you.”

Daugherty shared his letter with the public, but it's not the first time he has talked publicly about Jillian. Jillian's marriage is the latest chapter in an ongoing story captured at length in her father's memoir about raising her, "An Uncomplicated Life."
