Old quilt questions and information?

I have a few old quilts given to me by my sons great great grandma...anyway..it looks like handpicked cotton for batting and red, white and blue colors and very old in appearance which also is hand stitched. It has prints of old feedbag sacks on the back that reads: ROLLER MILLS DANVIILLE,KY ANDERSON AND SPILMAN Fulton Bags Atlanta 100 LBS. (NET WHEN PACKED). and something about using SNOWFLAKE FLOUR. How do I get it appraised? What could it be worth? Who would I take it to? Does anyone know anything about ROLLER MILLS in Danville, Ky? Any info would be awesome! Thanks in advance
