Rosemary Plumbley Gibbens Cox, 89, formerly of Marfa, passed on to her heavenly home quietly on February 20, 2019 in San Angelo.

Services will be on Saturday, March 2 at the First Christian Church of Marfa, where she was a lifelong member, with an informal viewing at 9:30am and services at 10am. Burial will be in the Marfa Cemetery.

Mrs. Cox was born in El Paso September 23, 1930 to Scott Lee Plumbley and Julia Marlowe Ellison Plumbley. At the age 14, the family moved to Marfa, back to her pioneer roots, as she was a member of an early pioneer family, the Ellison’s, who came to Presidio County in 1883.

She loved Marfa and developed many lifelong friendships. Some of her most fond memories were horseback riding from one end of town to the other.

She graduated from Marfa High School in 1947, then attended Texas Christian University and Sul Ross State University, where she received her Bachelor’s degree in education and a Master’s degree in counseling. She taught school in Norman, Oklahoma and Marfa for 30 years.

Rosemary married Ernest Gibbens Jr. in 1949. They had three sons, which she often said was her greatest joy: Ernest Scott Gibbens married to wife Linda residing in Lance Creek, Wyoming; John Lee Gibbens married to wife Margaret residing in Rocksprings, Wyoming; and Gene Clement Gibbens married to wife Laurie living in Sonora, Texas. Her legacy continues with six grandchildren, nine great-grandchildren, and three great-great-grandchildren.

Rosemary later married Buster Cox, sharing a ranch life raising quality Hereford cattle and Quarter Horses. This was a time she reflected fondly upon. She maintained her love of horses and dogs throughout her long life.

In lieu of flowers, memorial donations may be made in her honor to the Marfa Public Library and the Marfa & Presidio County Museum.
