Character Details

Joanie and Haley Clark were introduced as sisters in the very first episode I/O.

Puzzle for contributors to solve

What's not immediately clear is WHO played each character In that first episode, or if there were multiple players contracted. IMDb list TWO actors for each role in I/O as bellow:

 Joanie Clark was played by Morgan Hinkleman AND Maggie Elizabeth Jones 
 Haley Clark was played by  Alana Cavanaugh AND Lillian Ellen Jones

Maggie Elizabeth Jones and Lillian Ellen Jones are sisters and disappear from the credits after episode 1, with Morgan Hinkleman and Alana Cavanaugh taking over the role for the remainder of Season 1. Yet the mystery remains WHY are there TWO players for each role.

YOUR Job, dear Contributor, is to ferret this information out!

AMC does not list either Maggie Elizabeth Jones and Lillian Ellen Jones in the credits on their website for I/O

Yet we've often heard IMDb takes their data from actors Equity contracts so which is correct?

And if IMDb is correct, why the change mid-episode -- WE WANT to know!

Sisters Maggie Elizabeth Jones and Lillian Ellen Jones don't have a website listed on IMDb, Maggie has a Wikipedia entry, which DOES NOT list HACF, and Lillian does not have a Wikipedia page. We have attempted to find their websites, or agent website for the client and cannot.

So dear contributor, multiply our research capability and track this down. Inquiring minds WANT TO KNOW!!!
