She has four other siblings; her twin brother, Tommy; and Mickey, Bill and Marie Horton.

She was first married to wealthy banker Ben Olson and had two children with him, Steve and Julie Williams.

Addie soon gave birth to her and Doug's first and only child together, a baby girl named Hope.

As the only child of Tom and Alice's that died young, Addie was always an inherently emotional subject.

Even while other long-gone members of the Horton clan get pruned off the family tree (Steven, David, Scotty, even Tommy), Addie remains a central part of it.
