My paternal Grandfather had two sons. My Dad had two sons (plus two daughters) and my Uncle had three sons.
This photo of us male grandchildren was taken in the mid-1950s in Storm Lake, Iowa. Jeans and white T-shirts were in fashion then. From left to right: brother Kelvin (most handsome, passed away three decades ago), cousin Jeff, me, cousin Tim (passed this year), and cousin Michael (probably the most successful professionally of us: a Texas attorney).
