She was a strong and independent woman with a determined spirit, a will of her own, and an energy that was difficult for anyone to keep up with. Throughout her life, her family, faith, work, and community remained important parts of who she was. Mary enjoyed shopping and always took pride in looking her best. She had a generous heart and never hesitated to help someone in need. If someone needed a helping hand, Mary was there. Through her work with Amigos Del Valle, she was able to help many people in her community, always willing to do whatever she could to make a difference in the lives of others. Mary was a devoted mother and grandmother who cherished her family. She is survived by her children, Juan Antonio “Tony” Garza, Maria Guadalupe “Lupita” Garza, Jose Fidencio “Joe” Garza, Maria Milagros “Millie” Garza, and Juan Francisco “Franky” Garza Jr.; their spouses; 15 grandchildren; 10 great-grandchildren; her beloved brothers and sisters; and numerous other family members and loved ones. She was preceded in death by her parents, Francisco Trevino and Silvestra Mendosa; her grandfather, Nicolas Conde; and three brothers.

Burial will follow at Ashland Memorial Park Cemetery in Harlingen, Texas. Pallbearers will be family members. Mary’s life will be remembered not for what dementia took from her, but for all that she gave throughout her life. She will be remembered for her strength, her faith, her independent spirit, her generosity, and the countless ways she cared for and helped others. Most of all, she will be remembered for the love she shared with her family and the many beautiful memories she created with those around her. Mary was deeply loved, and her memory will remain forever in the hearts of all who knew and loved her. She will be greatly missed.
