Thank you so much! Very helpful!I'm pretty sure it's Edwin B. Root. Not sure what his role was, but some Googling reveals that he and K.C. Gillette were trustees on a family trust, in which there was some minor (very minor, based on my reading) legal drama. The matter I found was from 1932, for reference. Gillette v.
