Eugene Ray Gilfillan (1891-1973) was the father of Clyda Colene Gilfillan (1922-2010) who was the grandmother of Curt Bright.
I remember my grandmother Clyda saying that her father had served in the army, perhaps in Mexico.
This World War I draft card shows that Ray was a “sargent” for “about 14 months” in the Missouri Militia (4th Regiment Infantry). Ray claimed exemption from the draft on the grounds of “dependent and occupation” (farmer). Since he didn’t have any children in 1917, the dependent to whom he referred must have been his wife, Emma Helen (Buntz) Gilfillan.
The draft card also shows that Ray was “tall” and “slender” with “grey” eyes and “light brown” hair.
