Born in Sanderson, Texas, on June 27, 1937, to Francisco and Gudelia Lopez, Guadalupe lived a life marked by unwavering dedication, quiet strength, and distinguished service to his country. He proudly served in the United States Army during the Vietnam War and retired as a First Sergeant, a leader known for his valor and mentorship.

Guadalupe served his country with honor and distinction during both wartime and peacetime. His military career took him overseas to Vietnam, Korea, and Germany, and stateside to Fort Hood TX and Fort Dix NJ. He was a proud member of the infantry and armor divisions, demonstrating unwavering dedication across every assignment.

After retiring from the Army, Guadalupe continued serving his country through civil service. He worked in Special Weapons at the former Kelly Air Force Base and later with the U.S. Postal Service in San Antonio, dedicating over 20 years to federal service with the same commitment and discipline that defined his military career. He was also a member of the Knights of Columbus in Copperas Cove, TX.

Guadalupe married the love of his life, Maria Eleonor Barron, on October 8, 1960, at San Juan de los Lagos in San Antonio, TX. Their enduring love spanned more than 64 years, a testament to their deep devotion and partnership. Together, they built a life full of family, faith, and unconditional support—leaving behind a legacy of love that continues to inspire all who knew them.

He is preceded in death by his wife Maria; his parents Francisco and Gudelia Lopez; sisters Gudelia Lopez and Tomasa Perez; brother Francisco Lopez Jr.; and grandson Edwardo Gonzalez Jr.

Outside of his military and professional life, Guadalupe had a deep passion for working with his hands. Whether it was restoring cars in the driveway or fixing anything that broke around the house, he took great pride in being his daughters' personal handyman. From leaky faucets to broken appliances and ceiling fans, no project was too small for him—his quiet dedication and problem-solving spirit brought comfort and care to those he loved most.
