Mary Lou was an Amarillo resident most of her life, but she moved to Houston in 2015. Mary Lou was born October 8, 1924, at her parents’ home in Glasscock County, to Lewis Jerome Medlin and Mary Lydia Ward Medlin. She graduated from Garden City High School as class valedictorian in 1942. She attended Texas Technical College, where she was a home economics major.

In 1944, she left Texas Tech to marry Joseph L. McGregor in Austin. They followed Joe’s career, and moved to Amarillo in 1946, where they joined First Christian Church (Disciples of Christ). Mary Lou and Joe moved to Abilene in 1953, and they returned to Amarillo to stay in 1957. Mary Lou was an active and dedicated member of First Christian Church, where she served in many volunteer roles in the church, including as a deaconess, leadership of Christian Women’s Fellowship, women’s Circles, and Ruth group.

Mary Lou’s central focus was her family. She reared two daughters, serving as an adult leader for Brownie Scouts and Girl Scouts, supporting both daughters in their academic and musical studies, and in children’s and youth activities at First Christian Church. In addition, she was an expert seamstress who created unique clothing designs for both daughters, helping the girls to choose fabrics and patterns, including formal dresses for dances and recitals. To each design, she brought her own special touches and craftsmanship.

After her daughters graduated from high school, Mary Lou became an administrative assistant for Maureen Daniels Real Estate. She and Joe were accomplished square and round dancers, and they danced for 45 years. Mary Lou and Joe also loved to travel, and enjoyed many wonderful trips throughout the United States, Canada, Mexico, and Europe, often in the company of Mary Lou’s brothers and sisters-in-law. Throughout her life, she was an avid reader, and she especially enjoyed the historical fiction genre. Bridge and dominoes were other favorite pastimes.

A few years after Joe’s death, Mary Lou embarked on a new adventure, leaving Amarillo for Houston, where she made new friends, won untold numbers of bridge games, and explored life in Houston. She became a member of St. Luke’s United Methodist Church, where she supported the music ministry. She continued to travel for a few years, enjoying Texas, New Mexico, and Colorado with her family.

Survivors include her daughters, Patsy McGregor Sadowski and son-in-law James W. Sadowski, Shirley McGregor Pearson and son-in-law Michael P. Pearson, four wonderful grandchildren and their spouses, and two deeply loved great-grandchildren.

The family suggests that memorials be made to the music ministry at St. Luke’s United Methodist Church in Houston, TX, to the music ministry at St. Peter’s Episcopal Church in McKinney, TX, or to Houston Hospice, who provided support and comfort to Mary Lou and her family during the last months of Mary Lou’s life.
