Does anyone know what happened to Rube's brother Johnson Foster?

Ty,

I don't think Johnson had a bball connection like Rube as references to him are rare.
I found a SABR reference:
only he and two of his siblings, Christiana (born 1877) and Johnson (born 1884) survived until adulthood. The lives of Foster’s other siblings were taken by tuberculosis, a disease that undoubtedly impacted young Andrew’s interest in baseball. Foster himself said that “if it hadn’t been for playing ball and living outdoors, I don’t suppose I’d (be) here today.” [4] Physicians during Foster’s childhood indeed felt that spending time outdoors was the only way to avoid catching tuberculosis, a belief that only affirmed Foster’s interest in baseball.
Found a pic of Rube's gravestone in hopes to see Johnson on it also but no luck.
Good luck, mike
