William P. Thibadeau Jr. is the son of William P. Thibadeau and Anna McDonald, of Oshkosh, Wisconsin.
His father is the son of Gilbert Thibadeau and Catherine Casey. Catherine's father, Patrick, is my grandfathers brother.
I am researching what he was doing in the war when he went missing. According to his death record he was awarded the Purple Heart Medal and the Air Medal.
