Susan was born March 8, 1952 in Vicksburg, Mississippi and died in on April 12, 2026 at Presbyterian Hospital, Dallas, Texas.  Predeceased by her parents Edward and Susie Hullum Irby,  she is survived by her significant other, G. David Garber, her brother Edward (Buddy) Irby Jr., and his two children whom Susan adored, Nate Irby and Erin McCuller, as well as numerous Mississippi cousins. 

Susan graduated from Northeast University in Monroe, Louisiana.  She began work at the Bernini Law Firm in Vicksburg and Jackson, Mississippi and soon got her paralegal certificate.  She left for Dallas in the 1980’s working in the Trust Department of Republic National Bank.  Susan became an independent petroleum landman not long afterwards.  She partnered with another petroleum landman, and a geologist to form Dallas Petroleum Partners.  Their primary work was in Kansas, Oklahoma, Texas and Louisiana.  Susan loved all the travels involved from the spudding of wells to working with people at the state and federal levels in meeting all their requirements.  She was truly dedicated and loyal to her clients. 

Susan was a member of the Dallas Association of Petroleum Landmen, and served as President, as well as a member of the American Association of Professional Landmen.  She served on and coordinated the North Entrance Host Team at Canyon Creek Presbyterian Church, which she considered to be her care ministry to those with limited mobility who frequented “our door”.  Having no children of her own, Susan was nurturing and endearing and was a godmother to friends’ children.  She enjoyed watching the children of neighbors grow into adulthood. 

Burial will be next to her parents in the family cemetery at Antioch Cemetery Association in Vicksburg, MS.
