What is the venue for obtaining these microfilms you mentioned? The name Heffiner is extrememly uncommon in 1860-70 Census and I can not help but imagine that J. L. Heffiner in pardnership with Robert J. Reed, running a saloon, is the same Heffner as in "Heffner, McClain and Cooper who "worked four men at a sluice on the Clay County Lode, averaging $100.00 a day for ten weeks." (History of Colorado, Vol. I p. 245 ed. W.F. Stone.) and most likely the "Colonel Heffiner" of Maces Hole.

In your search for John H. Gregory what did you think of the essay by Patsy Bradbury: John H. Gregory

What struck me in her essay is the finesse by which Green Russell used his Masonic connection to make his way through Union obstruction to Confederate connections to the Colorado gold fields.
