George Malcolm Glavin
October 17, 1921
May 18, 1991
1939-40 Ballard High School - Washington (High School)
1946-47 Seattle Blue Devils (PCBL)
1947-48 Seattle Athletics (PCBL)
Pretty certain the Seattle player listed in a few box scores as "Glavin" is George Glavin, the team's business manager.
Evidence shows this player is William "Billy" Galvin, 6'2 185 pounder who allegedly went to Univ of Washington. However, no Galvin appears on UW roster.
