Her kind nature knew no bounds as she dedicated herself wholeheartedly to nurturing her son Mason and creating a loving home for her husband Trevor.

Margaret faced numerous challenges throughout her life but emerged stronger each time. Once she found God, He helped her to transform her life. She loved and the relationship she had found with him, and we know that she was welcomed into His loving arms.

From overcoming personal obstacles to carving out a better future for herself and her family, she was the epitome of resilience. Margaret’s accomplishments were a testament to her unwavering determination and indomitable spirit. Her journey inspired everyone who crossed her path.
