It's been awhile since I was searching... however to answer your question, I believe he was named after his Dad. Grandfather was Lucian Paul Gravelle, Father is George Paul Gravelle (only child). Grandfather was married to Leona M "Bille" Swan. Grandfather was born in Minnesota, the Duluth area I believe. Later lived in Washington, Indiana and worked for Superior Steel Ball Company. Later I believe he lived in Connecticut.
