[KS] A final question

[Brother Anthony]

I promise that I will not write again until next year, but I would be more than grateful if somebody could provide me with the dates of birth and death of C. T. Collyer. 

Charles T. Collyer was a Methodist minister who worked in the region of Songdo (Kaeseong) in the early years of the twentieth century. He first arrived in Korea in January 1897 and left in 1919. In November 1920 he arrived in Prague, Czechoslovakia, where he worked selling bibles ("colportage") until late in 1923, when he returned to the US.

That much is clear, and that he wrote about ginseng and that his wife died of pneumonia in Pyongyang in 1909, I also know. But I would really like to know when he was born and when / where he died. Google refuses to tell me, which is unusual.

And a happy new year to all
