    Karla, Charlie, Sheryl and Isla. My heart is with you during this time of sorrow. I remember the day Marky was born. I was the first relative besides his mother and father to welcome him into this world along with his father's navy buddy Steve Reed. In 1992 when Marky and his family moved to South Dakota I said to myself that one day I would see him again and in 2006 I did when he was stationed at Fort Hood. Now in 2026 he leaves again and once more I say to myself I will see him again. Rest in peace nephew. Love Uncle Kris

    I'm very proud of My Cousin for his military service. I'm also very thankful for it since it brought him to Texas where I could spend time with him. Time during which there was lots of trash talk, beating each other up & lots of laughs. Aunt Karla & Cousins, you are in My Prayers. Thank you for the memories, Marky, I Love You, Cousin!! May You rest in Peace. Love, Tiff

    Karla we are so sad to hear of the loss of your son, Mark. I know you were so close. A mother should never have to beat the loss of a child. Our thoughts and prayers are with you. Steve and Linda Varvel

    Mark Gillen was assigned to my squad during A Troop, 4-9 Cavalry's 2006-2008 deployment to Iraq. He was a spark plug of pure, unbridled energy and confidence which was in equal parts obnoxious as it was endearing. Never have I had a Soldier so motivated and loyal. He never knew how much he did to keep my cynical and jaded veteran mentality from going too dark. Save us a seat at Fiddler;s Green, Mark!
