You mean Maureen who was supposedly named Dawson and had a sister named Cissy? There are a couple of pictures of them on another thread here, but of course I can't find it now.
In this picture in the center background with the long hair and large areoles is Michelle Angelo, who appeared in a lot of nudist and figure magazines and a few films in 1967-68 to earn money while her husband was in school. She has a website and seems amused by the attention and notoriety now.

If you have the time, could you post more pictures from inside the magazines as well as the covers?
