This home was built after World War I, in 1921, using the Georgian Colonial Revival style of the era. The first residents were Adeline “Addie” and Dennis T. Flynn.

Dennis, born on February 13, 1861, in Phoenixville, Pennsylvania, was raised in an orphanage after his mother died when he was three years old. In 1882 he moved to Kiowa, Kansas where he served as postmaster, city attorney and the publisher of the Kiowa Herald. In 1887 Dennis married Addie who was born in 1859 in Kansas. In 1889, Dennis was named the first postmaster in Guthrie, then served four terms as the territorial delegate to Congress. Dennis and Addie had four children, Dennis, Dorothy, Streeter and Olney.

When they bought the house on 15th, Dennis was an attorney with another Heritage Hills resident, C.B. Ames and a director on the boards of six industrial and financial firms.

After the Flynns moved out in 1924, the home changed hands several times, the longest resident being Dr. Lelia Andrews, who lived here from 1927 to 1946 before moving to the smaller house next door at 509. Dr. Andrews was born August 14th, 1876, in North Manchester, Indiana. She received her medical degree from Northwestern University in 1900 and opened a practice in North Manchester. She later moved to Oklahoma City in 1908 to open a general practice. She became an instructor in pediatrics at the University of Oklahoma College of Medicine in 1910 and an associate professor in 1915, serving in that position until 1925. She was one of the first two women admitted to the American College of Physicians in 1920. Andrews also worked at St. Anthony’s, Wesley, and University hospitals. Dr. Andrews died in her home on April 28, 1954, at the age of 77.

In 1975 the home was purchased by Dianne and William Dow “Bill” Gumerson. Bill was born on October 2, 1944, in Minneapolis. He spent his early years in Enid, Oklahoma and graduated from Harding High School in Oklahoma City in 1963. Bill attended Oklahoma State University and the University of Oklahoma. Bill was the founder of Bill Gumerson & Associates, a design-build firm focused on new construction as well as restoration of historic properties. Bill served on many community boards including Historical Preservation, Inc., the Oklahoma City Historic Preservation Commission and Preservation Oklahoma, where he led the capital campaign to renovate the exterior of the Overholser Mansion.

Dianne was born January 1, 1944, in Oklahoma City. She graduated from Harding High School in 1962 and then attended the University of Oklahoma. She served on many community boards including the Junior League of Oklahoma City, Oklahoma City Arts Festival, Oklahoma City Philharmonic Symphony Orchestra, Overholser Mansion, Heritage Hills Associate Board, and the Chafing Dish Society.

Dianne and Bill were high school sweethearts who married in 1966. The Gumersons completely remodeled the kitchen, added a swimming pool in the backyard, converted a third-floor attic to a playroom for their three children, Kristen, Katie, and William. The family enjoyed snowskiing and trips to the lake. Bill and Dianne were married for thirty years until Dianne’s death on April 8, 1996, at age 52. Bill died November 26, 2020. Their daughter Katie continues to live in Heritage Hills with her husband, Brooks, and their children. Brooks also grew up in Heritage Hills.
