Help separate out the "Sally Marr"s

The page of Sally Marr (I) at https://www.imdb.com/name/nm0550022/ is apparently supposed to be primarily for Lenny Bruce's mother, who lived from 1906 to 1997.

However, I found there was a TV Guide from Nov. 21, 1970 (https://www.tvguidemagazine.com/archive/suboffer/1970s/1970/19701121_c1.jpg.html) which featured on its cover "starlet Sally Marr" under the headline "What it takes to be a starlet in the '70s". The woman on the cover is clearly not the Sally Marr who was Lenny Bruce's mother, who would have been 63 years old at the time.

But there's only one other Sally Marr listed in IMDb -- Sally Marr (II) at https://www.imdb.com/name/nm5594526/ -- and she doesn't have any credits besides a director credit in 2005, thirty-five years after that TV Guide cover.

I found a blog post at https://www.itsabouttv.com/2020/11/this-week-in-tv-guide-november-21-1970.html which discusses the issue that the Sally Marr (I) page has conflated two women with each other, Lenny Bruce's mother and the 1970s starlet. Here's what it said:

Our guide through this odyssey is Sally Marr—not the Sally Marr who was Lenny Bruce's mother; no, our Sally is 29, from Texas, and is the starlet of today: "creative but no aesthete, not beautiful but gives the illusion of classic beauty; she wants to be an actress not a star; she is, above all, nonconformist. . . She doesn't go to Hollywood parties, chic eating places, premieres, or any other place which might be politic for her career if she wanted to be the starlet of the year." ...

When she got tired of modeling in Paris ("We were doing bathing suits on the Seine in the middle of winter"), she moved to London, where she appeared in Harper's Bazaar, Vanity Fair, Flair, and other fashion mags. That's where she met her current boyfriend, John Bloom, who accompanied her to New York, where she made a movie called The Drifter that "won a lot of prizes at the Venice Film Festival." While in Los Angeles, she did more modeling, and found herself doing roles in movies and television shows: Mayberry RF.D., The Men from Shiloh, and besides her modeling, "now I've got a great role in an Italian film. Right on."

As I said, quite a story, isn't it? So no sitting around at Schwab's Drugstore in a tight sweater waiting to be discovered; this, apparently, is how it is to be a starlet nowadays. And, especially as a model, she's had a good bit of success. But I know, you're all wondering how this story ends. I wish I could tell you, but the not-always-reliable IMDb has failed in this regard. For example, the episode of The Men from Shiloh that she did? According to IMDb, that was the other Sally Marr, Lenny Bruce's mother. Then there's an episode of the 1979 series A Man Called Sloane called "The Seduction Squad" that features international supermodels brainwashed into engaging in industrial espionage (which I suspect happens all the time)—"Sally Marr" plays one of the models, but considering that she was 73 at the time, I rather suspect that this could have been our Sally as well. And there's The Facts of Life Goes to Paris, made in 1982, and—hell, who knows what the truth of the matter is? It proves the importance of research—good research, not just easy research. There is more than one Sally Marr in the world.

Yes, I know that with a bit of that good research and a little effort, I could get to the bottom of it all, but as much as I love all of you out there, I'm not about to spend hours of my life trying to find this out just to write one paragraph for this article. I'm sorry, but that's the way it is. Now, if any of you want to take it on. . . 

I note that there is only one movie titled The Drifter listed in IMDb -- The Drifter (1966) -- and the top-billed actress listed there is Sadja Marr -- quite possibly the starlet we are looking for using a different first name. (Although I can't find any evidence that this movie won any prizes at the Venice Film Festival.)

Well, I can't sort this out any more than the blogger was willing to, but I'm raising this issue in hopes that someone will be willing to sort out this problem.
