Susan Marie Hathcoat

Susan Marie (Siems) Hathcoat went to be with the Lord early Monday morning, May 11, 2026.

Susan was born in Houston, Texas, on July 13, 1954, to Willie and Frances Siems. She was preceded in death by her parents, as well as her uncles, Donald Siems and Henry Biles.

She is survived by her loving husband, Daryl Hathcoat; her son, Dusty; her brother, Billy Seims and wife Caye; and her beloved granddaughter, Peyten. She also leaves behind numerous nieces, nephews, cousins, and many others who lovingly knew her as “Nana.”

Susan spent her early childhood in Houston alongside her brother Billy before the family moved to the country near Highway 290, long before the area became what it is today. There, surrounded by cows, chickens, and open land, Susan formed friendships that would remain with her throughout her life. Among those friendships, none was more special than the lifelong bond she shared with her dear friend, Scarlett.

She attended Cy-Fair High School when it was the only high school in the Cy-Fair Independent School District. Following graduation, Susan attended the University of Houston for a few years before deciding to pursue a different path in life.

Throughout the years, Susan worked for several companies before eventually dedicating herself to caring for her family. After her father’s passing and following her mother’s stroke, Susan lovingly stepped away from work to care for her mother full-time.

In November of 1981, Susan welcomed her only child, Dusty, into the world. In January of 1994, she married the love of her life, Daryl Hathcoat. Susan also became very close with Daryl’s youngest son, Richard, who spent many summers with them despite living out of state.

Faith and family were at the center of Susan’s life. After her mother’s passing, she devoted much of her time to serving alongside her dear friend Nancy Bergeron in children’s ministry at The Met and Jersey Village Baptist Church. Susan assisted with weekly programs, Vacation Bible School, and countless other activities supporting children and families through the church.

Susan deeply loved her church family and especially treasured the Bible study group she and Daryl joined in 2005. Even as members moved away from the Houston area over the years, the friendships and bonds remained strong.

Above all else, Susan had an extraordinary heart for children. While she may not have had any grandchildren by blood, she was truly “Nana” to countless children whose lives she touched with love, compassion, and care.

One example of Susan’s caring spirit began nearly twenty years ago during a church service focused on sponsoring children overseas. Alongside a young Abby, Susan chose to sponsor a four-year-old little girl from the Philippines. What began as occasional support through a ministry eventually became a deeply personal relationship. When the original organization stopped supporting the school, Susan searched for and found the family herself. She remained in contact with them for years, helping provide food, supplies, and encouragement to the family and their four daughters. Even after the girls lost their father, Susan continued to stay connected with them. To those children, Susan will always be remembered as their Nana.

Susan’s love extended to many other children throughout her life. Abby became like a granddaughter to her from a very young age, and despite disliking cold weather, Susan faithfully traveled north for many years to visit her after her family moved away.

She also shared a special bond with the Johnson family and their twelve children, several of whom were adopted and had disabilities. Susan celebrated birthdays, attended gatherings, and continuously showed up for them in meaningful ways far beyond holidays or special occasions.

Peyten’s sisters, Hallie and Madison, also became deeply connected to Susan after returning to Houston.

Susan especially cherished her role in Peyten’s life. When it became clear that Peyten would not be able to go home with her parents after birth, Susan stepped forward without hesitation, determined to give her a loving home and family.

Susan also adored Caden, Daryl’s grandson and Richard’s son, who spent much of his early childhood with them before moving away.

Susan was a loving wife, devoted mother, and cherished Nana whose compassion touched countless lives. Though the last several years were difficult as her health declined, her love for others never faded.

She will be deeply missed by all who knew and loved her.
