Welcome to Websleuths, Holly, and thanks for caring about El Dorado Jane Doe. I'm really looking forward to the day she is identified, too.
I don't want to discourage you but Charlotte Loomis (5'2 at age 14) and Mary Rodermund (5'4 at age 16) are both too short to be EDJD, who was 5'10 or 5'11 (which is roughly the average height of an adult man, noticeably tall for a woman).
Keep in mind that women reach their adult height around 15-16. It's rare to keep growing after that, especially not a huge growth spurt of 6 inches+. And since her body was found within hours of her murder, we can assume her height is a reliable measurement, unlike decomposed or skeletal remains where they have to estimate the height based on the length of bones.
EDJD is one of the most famous Jane Doe cases in the USA, so pretty much every likely candidate listed in missing person databases has been suggested by now. Might I suggest you put your search efforts toward a lesser-known case? There are so many John and Jane Does that deserve more attention. Here's the NamUs unidentified remains search link:
The National Missing and Unidentified Persons System (NamUs) - you can narrow it down to cases from a particular time period, age group, location, or whatever interests you. For example, if you search for only women found in 1991 with the age estimate set to 18-30, there are 50 results!
