Burial Date: October 16, 2020. Jennifer “Jen” Marr (nee Gau), 46, died Oct. 9. Jen was a dedicated mother first and foremost. She is survived by her three children, who were her entire world: James, 15, Andrew, 13, and Samantha, 10. She embraced every moment she had with them and devoted her life to caring for them, including countless trips to practices, games and competitions. Jen’s love and affection for James, Andrew and Samantha is immeasurable, unconditional and eternal, as is her devotion to God. She loved deeply. She was always willing to help whenever a need arose. Jen’s servant heart, which she inherited from her mother, led her to volunteer often, primarily at Queen of All Saints Parish, where she led school fundraisers and worked with the activities association. Jen was a proud graduate of St. Margaret Mary Alacoque, Cor Jesu Academy and Rockhurst University. She worked at Bethesda Southgate as an occupational therapist, where her vivacious personality will be greatly missed. She had an irrepressible smile and booming laugh that could be heard across the room. She shared her love of the St. Louis Cardinals with her children and made friends wherever she went.
