Clara Gow was my aunt. I'm the youngest child of Leo and Barbara Pedtke. My father was the oldest of 12 children, his father was Herman Pedtke. There were 10 boys and 2 girls in the family, the girls were Clara and Theresa. The boys were Leo, Joseph, August, Henry, Daniel, (and several that died in infancy). My grandfather and my father and 2 of his brothers manufactured pianos back in 1915 until about 1918 under the name Herman J. Pedtke piano company. My grandfather was a cabinet make by trade and my father was a piano technician. So, grandpa made the cabinet and my dad made the action of the piano. These pianos are still listed in piano books.
