Concerning Search for Tomorrow, around the time that Denise Nickerson was playing Liza, Michael Maitland was hired to play Bruce Carson. He played Bruce in between Robby Benson and Gary Tomlin.
Also, I think that Kitty Styles and Ken Stevens (Diana Millay and Joel Crothers) were on The Secret Storm at the same time.
When Christopher Pennock was on Somerset, Frank Schofield played his father. The actor who played Carter Mattson (Jay Gregory) had also been on Dark Shadows as an extra. Lois Kibbee played the wife/stepmother, and she, as was mentioned, co-wrote The Bennett Playbill with Joan Bennett.
The information on Jonathan Frid is incorrect. He did appear as Dr. Bellows on As the World Turns - not Dr. Neil Wade. That role was played by Michael Lipton, who was also on Somerset when Mr. Schofield and Mr. Pennock were on the show. (And Marie Wallace had been on the show, also.)
As the World Turns also had a mean character named Dr. Michael Shea. John Lasalle (Dr. Gutherie) was one of the actors who played that role, but the actor best remembered in the role is the late Roy Shumann.
When Sam Hall was writing One Life to Live, there were three former Dark Shadows performers on the show at the same time: Nancy Barrett, Anthony George, and Grayson Hall. There was a scene in which the three were together - possibly in an elevator - and they commented that they thought that they had known each other before they had been in Llanview.
Matthew Hall was also a writer for One Life to Live. He later wrote for the NBC primetime version of the Dark Shadows.
