This Saturday I came across what I believe is the same raccoon and she is bigger and her face is whiter! Perhaps the pigment fades with age. However she was quite agile and climbed a tree to sit on a large branch and groom herself.
It was wonderful to see her again and to know she is fine and healthy. I checked into the lifespan of raccoons and from various sources found a range of 3 years to 10 years in the wild and up to 20 years in captivity. I hope she has a long, happy life.
