What a beautiful quilt you have. You are so lucky to have something that old and still in such great condition.
I am not a quilt appraiser or authority, by any stretch of the imagination. But I do LOVE antique quilts, have studied them some, and have been to quite a few exhibitions.
Applique quilts made with turkey red and over-dyed green fabrics were very popular in the mid 1800s. Here are some links you may find interesting-

I would definitely have your quilt professionally dated and appraised.
