Who is this 83 year old lady on the JMT?

On July 19, we met Adam (forget his last name) and his grandma, who is 83 years old. She has thru-hiked the JMT 7 times, she was not able to thru-hike it this year due to foot injuries. I think her first name is Rose but may be wrong. She had done the PCT, thru-hiked 2 or 3 times. Supposedly she is quite famous on the trail. Does anyone know her and how old she was on her last thru-hike of the JMT — she may have beaten Dale's record of age 75 (Dale
Easton (age 75), completed the trail SoBo this year in 21 days (July 19 to August 10)). She had planned to hike the JMT with her grandson, Adam, but in the last month injured her foot. Funny story, Adam accidentally hiked off onto the JMT with the car keys that his grandma was supposed to drive back and she caught up to her grandson with an injured foot and here she is about 4 hours into the JMT without showing a sweat broken — notice how much sweat, Adam has.

Thanks for any of your help.

Here is a picture of Dale Easton, age 75, who thru-hiked the JMT this year (we saw them on 4 different occasions throughout our JMT hike). The taller person, is Alfred Patrick, age 71 (then) now age 72. He thru-hiked the JMT with Dale. Dale's name and accomplishment officially makes him the oldest recorded JMT thru-hiker and reportedly, the JMT record holding web page is being updated about this.
