Obituary for Mary ‘Colleen’ McCormick

Mary “Colleen” McCormick, of York Valley, quietly passed away on May 30, 2020, with her family at her side.  She was born on Feb. 14, 1931, in Kayenta, Arizona to Lloyd Albert Wiltse and Mary Mann Wiltse, with siblings Lloyd and Anna Marie Wiltse. 

Colleen went to Ajo High School and then went on to marry Rolland J. “Red” McCormick on Dec. 28, 1948, while still in Ajo. The couple was blessed with three sons; Dennis, Stanley, and Jim.

She loved crafting, gardening, landscaping, camping, sewing, and sitting outside watching the birds while listening to music. She was a caring, loving, and compassionate person. Colleen and Red celebrated 71 years of marriage this past December, something very few couples accomplish.
