My grandpa and Theodore were cousins. My grandpa also played the organ in the Lutheran church where I grew up. My grandpa is the reason I wanted to learn piano and organ. And why I wanted to play the organ in church like my grandpa. I knew about Theodore from my grandparents. I have only one of the Stelzer's Sacred Song Series books. I have a copy of A Child's Garden of songs. Loved hearing about my relative. Thank you!
