Watts was born and reared in Homer and settled in nearby Lufkin after her marriage in 1889. Save for brief instruction from E. Richardson Cherry and Hattie Palmer, Watts was a self-taught artist who specialized in forest scenes that reportedly numbered over a thousand. Her painting The Virgin Pines of East Texas was reproduced in 1927 on the cover of the Texas Federation News. She reportedly exhibited a painting at the 1933 Century of Progress Exposition in Chicago. Watts died in Lufkin.
