Dianna L. Cochran-Leeper

Dianna L. Robison-Cochran, lovingly known to everyone as Nana, passed away on September 13, 2026, in Midwest City, Oklahoma. She was born June 1, 1960, in McLoud, Oklahoma, to Anna Mae and Everett James Robison.

Dianna graduated from Choctaw-Nicoma Park Schools in 1978, where she proudly played in the marching band. She went on to spend more than 27 years as a bookkeeper at Parker Brothers Roofing, where her love for numbers and her hardworking nature shined.

To know Nana was to know someone who loved deeply and gave endlessly. She was caring, hardworking, and loving, but above all, she was devoted to her family. She found happiness in karaoke, piano, darts, bingo, and all the little moments shared with the people she loved.

Her greatest joy was her family. She leaves behind her only daughter, Misti Blankenship and husband Randy; Grandchildren: James H. Roberts III (JR) and wife Chasity, Nicole Roberts, Matthew Millsap and wife Megan, and Samuel Millsap and wife Madison; and her four beloved great-grandsons: Tucker, Bellamy, Dax, and Hudson, who were truly the loves of her life. She is also survived by her sister, Jamie Klassen and husband Henry, great-aunt Bonnie Mullendore, and numerous nieces, nephews, cousins, and many other loved ones.

She was preceded in death by her parents, Anna Mae Wainscott and Everett James Robison; stepfather, George Wainscott; sister, Lela Robison; and grandparents, Rev. W.E. and Lela Mullendore. As well as her two previous husbands, two uncles, one aunt, and two cousins.

Nana's greatest gift was the love she gave her family. Though her hugs can no longer be felt and her voice can no longer be heard, her love will remain in the hearts of those she left behind. She wasn't just Nana—she was a piece of home, a lifetime of love, and a part of each of us that will never be gone.
