Bob:
I agree that Carder is full of mistakes and that is partly due to his having taken so much from Gardner, and others, without more independent research.
I had not read that Frank worked for Lefever before doing his best/worse in W. Va. and returning to New York.
Knowing no more than I do, I can't say yes or no.
As to using handles on a BBS---There are some valid reasons for doing so, but it is not valid to use one to make mischief. Long ago, I decided that I would never post anything that I would not say to a man to his face. I am. also, ready to admit that I make mistakes or that I may be in error. Wish more thought like this.
Best,
John
