Diane was a lovely lady and the world was a better place for her having been in it.

I have fond memories of spending time with Diane as a child and being her classmate at St. Hubert's grade school. While hospitalized at CMH some years ago I encountered her there as a loving and kind nurse. Dick and I both want to extend our deepest sympathy to the Brahm family.

She was my inspiration and our fearless leader. As my older sister, we had our differences but in the end we always ended up friends. I remember our ball playing years. She was our calm pitcher and led us to victories too. Her and I took tennis lessons together, we weren't the greatest but had fun learning together. I have many more fond memories that I will always treasure. I'll see you in heaven. Love always!! Jan
