This is the most fruitful search I have had so far. I'm only half way through and I already have the same number of potiential matches for the cheerleader in the trunk as I had for Castleberry Kate at the end of my search. There aren't as many long-shots with location on this list.
The Cheerleader in the trunk was a young woman, probably between 17-27 whose skeletal or decomposing remains were found in a poorly hidden trunk in the middle of nowhere in Frederick, Maryland. She had long hair, most likely brown or red, but possibly black because as we have seen with Arvin Jane Doe, hair can get lighter after death. Strawberry blonde may be a possibility too. Her body hair was Red, but the hair on someone's head can be lighter. They never did confirm or deny if her brown hair was dyed. Her height is 5'2-5'6 and her estimated weight is 100-130lbs. She had quite a thin nose and some distinctive injuries to her pelvis and ankles, which led the medical examiner to believe she could have been a cheerleader, athlete or dancer, hence the nickname.
I have scoured Charley project cases between early 1972 and mid 1977 so far. Anyone with overlapping front teeth, a gap between her front teeth, a denture plate or missing teeth was ruled out, as was anyone older than 29 or with an estimated height of less than 5'1 or more than 5'7. I only considered girls younger than 17 if there is a possibility they ran away and survived long enough to turn 17. It didn't matter whether the woman/girl had or hadn't given birth, as this is either unknown or not publicly available about the Cheerlder in the trunk.
The first three girls on this list are all from less than one hour away.
18 year old Diane Todd disappeared just 57 mins away and has not been ruled out as of yet:
The National Missing and Unidentified Persons System (NamUs)
14 year old Karen disappeared 53-55 minutes away and there is a decent chance she could have been a runaway. Therefore, it might be possible she lived to be old enough to be the cheerleader in the trunk.
Karen Beth Kamsch was a girl who went missing sometime in 1976. Her case is being investigated as a homicide. Although her family members claimed that they reported her missing shortly after her disappearance, an investigation in 2007 could not locate the original report. It is unknown if the...

25 year old Betty Irene Redmond disappeared 53 minutes away and has not been ruled out either. Her hair is described as black, but as I mentioned earlier, it may have gotten lighter after nearly 6 years in a trunk.
The rest of these are just in the order that I found them in.
18 year old Lynn Burdick disappeared 7 hrs and 12 minutes away. I still included her because her case is a pretty clear cut abduction, so there's a possibly she could have ended up as far away as Maryland.
Barbera was 23 years old and from approximately 10 hours away. For unknown reasons, prior to her disappearance, she'd felt the need to carry a knife for her protection. Her family aren't sure if she ran away or met with foul play, authorities believe the former.
Patricia Wagner was a 26 year old mother of two who disappeared after going on a date, about 3hrs 43 minutes away from where the body of the cheerleader in the trunk would be found years later.
21 year old, Rosemarie Roginski disappeared just 3½ hours away. The only pictures available of her are from when she was 16. If she let her hair grow longer and cut out her fringe since then, or between her disappearance and death she would be an exact spitting image of the Karl Coppleman reconstruction of the cheerleader in the trunk. (Even the teeth look the same)

29 year old Charlotte Brown is believed to have been killed by her spouse, just a little over 5 hrs away from where the cheerleader in the trunk was found. All 3 of her children said they saw her be stabbed to death.
Charlotte Elaine Brown was a woman last seen in 1973, after being dropped off by a friend at the “Rapid Transit” Station at 55th Ave., Cleveland, Ohio. She was the second wife of the man previously married to Darcy Brown, who disappeared in 1964 under suspicious circumstances. Brown hair. She...

26 year old Hazel Cross vanishd around 6½ hours away and her height lined up and she had a very similar nose and long brown hair, but unfortunately almost nothing is known about her disappearance, so without knowing anything about her dentals, it is hard to rule her out or in.

29-year-old Carol Louise Rodriguez was last known to be hitchhiking just under 7 hours away and she was never seen again. Just about anything can go wrong with hitchhiking. I wouldn't rule out her being driven to her killers house 7 hours away.

20 year old Rosemary Buck disappeared 5 hours away. If you don't take her hair into consideration, her facial features and shape are strikingly similar to the cheerleader's and they never did rule out her hair being dyed, hence why I believe this match is still possible.

Sheryl Tillinghast was only 17 years old and, similarly to Karen, not reported missing for a very long time - 25 years. Therefore, the wouldn't have known about her when the body was found. She disappeared just over 5 hours away.
Less than three and a half hours away, 18yo Sandra, or Sandy Hopper disappeared. She had some distinctive characteristics which could have been of help, but sadly none of them would have been noticeable on a skeleton, so again there is no way to rule her out or in without knowing her dentals.
Sandra "Sandy" Lee Hopler was a young woman who vanished from La Plume, Pennsylvania on September 29, 1973. She had told her roommate that she was going to take a trip to New York and she was last seen at a bus station that day. Light brown hair. Hazel eyes. Pierced ears. Mole on the back of...

21 year old Nancy Erickson vanished around 7 hours 21 mins away. The reason I still believe she could be match is because she may have been running from the law, and therefore very well could have travelled as far as Frederick Md.

24 year old Vickie Lee Lamberton went missing approximately 7½ hours away. The exact circumstances of her disappearance are unclear and her case is another one where she was not reported missing at the time the cheerleader was found.

29 year old Katherine disappeared from clearfield Pennsylvania and at some point after her disappearance visited a friend in New Jersey, asking her to send telegrams to her family and friend with whom she'd left her 4 children. From the sounds of things, she was at least initially planning to go back to Pennsylvania for her children. There is a route from New Jersey back to Pennsylvania in which she would have driven right through Maryland.
When I saw the picture of 23-year-old Mary Robinson, my brain instantly put her and the 8th reconstruction shown on the Cheerleader's wiki page together like two puzzle pieces. However, this is only possible if Mary's killer is lying about where he put her body, or if he got someone else to move her body, which would have probably happened around '79 (if it did happen) as that is when he confessed. He said he dumped her about three hours away, but Mary lived nearly 5 and a half hours away.
22-year-old Judy Sylvester is the only person so far who I've included despite the height being a bit off. It is only off by an inch of two and it is possible she was actually 5'2 as an MP's height is usually an educated guess from the family. She disappeared from 4½ hours away and very little info is available, sadly. But I thought there was enough of a resemblance to consider her.

29-year-old Leslie Guthrie vanished in February 1977, around 4 hrs 45 minutes away. Despite pretty much everything matching up, I really hope she is not Jane Doe, as she had her little girl and boy with her at the time of her disappearance.

Eddy Milta Segall was either 27 or 28 when she vanishd after borrowing her friend's car. The car was found abandoned in the woods, with some of her belongings still inside. This was approximately 8 hours, 20 mins away and may have been a case of abduction.
