Oliver McDowell (Mac) Stallcup passed away surrounded by family on January 8, 2019. He was 92 years old. He joins his beloved high-school sweetheart and wife of 61 years, Claire Cloyd Stallcup, who died in 2009.

After serving in the Navy during WWII, Mac made his career in the oil business. In 1968, he and a partner purchased the Tulsa-based J.E. Shaffer Co., manufacturer of the Come-Along. He ran the Shaffer Co. until retiring in 2010 at the age of 84.

In addition to his abiding love for Claire, Mac took enormous pleasure in his family. He was a devoted father to his three children and the quintessential family man. He adored his seven grandchildren and four great-grandchildren and was intensely proud of his entire extended family. His fifth great-grandchild was born just a few hours after Mac passed away.

Mac's charming personality made a lasting impression on everyone he met. A voracious reader, he was a keen football and basketball fan and enjoyed a good steak with his scotch.

Mac is survived by a sister, Sue Howell, of Greeley, CO, his children and their spouses: Kathryn (Katie) and Thomas Mustoe of Evanston, IL, John M. (Mac) and Melissa Stallcup of Jenks, OK, and Anne and John Faust of Houston, TX. Mac also leaves seven grandchildren and their spouses: Anthony and Alison Mustoe; Lisa Mustoe; Jason and Emily Yang; John and Julia Stallcup; Ellen Stallcup; Austin Faust and Lauren Faust. Mac's five great-grandchildren also survive him: Ben, Joshua and Hallie Yang and Brady and Lee Stallcup.

He will be deeply missed.
