I wondered if you have seen the letter sent to the Bureau of pensions in Washington DC by a Mrs Margaret Gibbs Bell (also of Washington DC.)
It was written in Jan.1921 and it is the place I get the suggestion of Rev. John's middle name as "Nicholas" from. I'll attach it to a email and send it to your personal email if you haven't seen it. Are you getting ready for another year there at school? Have a great day.
