My dad was a very loving, caring, and good hearted man. I never wanted for anything. Because he was my dad is why I am the man I am today. Thank you dad for always being there. I know you and mom are together watching over us. I love you!

Will always think about how he treated me like a son. Always willing to help me when needed. The trailrides, rodeos, the trips to the lake ,never a dull moment .

Rupert was my husband Ralphs cousin, but we all called him “Uncle Rupert”. We were neighbors for years in Somerset. Watched Jason grow up, saddened when Becky left us. Watched his grandchildren and children make him so happy. So many wonderful, fun memories of home, lake and midnight rides. We loved him and he will be missed. Prayers to our whole family. Love and hugs. Ann Cortinas
