A beloved wife, mother, grandmother, great-grandmother, and great-great-grandmother, Mary Anne's life was filled with love, laughter, and devotion to her family.
While Mary Anne had a lifelong career working for the government, most notably her many years at NASA, family was the center of her world.
She found her greatest joy in spending time with her "GRANDS", never missing a chance to celebrate their milestones and achievements.
She was the life of every family party, always ready for a game of Mexican train, a story by the fire, or a laugh on the beach. Her love for horses, the ocean, sewing, her friends, and her unwavering support for her family were constants in a life lived fully and beautifully.
Mary Anne's warm heart, fun-loving spirit, and deep devotion to those she loved will be remembered by all who had the blessing of knowing her. Her legacy lives on in the countless memories made, the stories, and the values she instilled in generations to come. Her family will carry on her legacy of kindness, strength, and resilience.
She was preceded in death by her husband, Joseph Robertson, with whom she shared many cherished years, and her stepdaughter, Julie Schweikert. Mary Anne is survived by her children Denise (late husband, Danny) White; William (Mary) Peterson; Joseph (Bridget) Peterson; and Scott Peterson; stepchildren Brian (Marty) Robertson; Wayne (Kim) Robertson; Kevin (Stephanie) Robertson; 14 grandchildren, 14 great- grandchildren; and 4 great-great- grandchildren; her brother, Henry Guyther, and sister, Kathleen (Dennis) Malcher.
