I thought of her when I saw that you were having Chuck Connor's son at the summer show.
With the exception of "The Rifleman", she was also a regular of the "Daniel Boone" TV series. But since then, she has seemed to have disappeared. I had the opportunity to meet Veronica Cartwright (who played "Jemima" on that series) about 7 or 8 years ago. I asked her about the latest on Ms Blair and she didn't have any idea what happened to her, where she currently lived or any news.
