I don't know if Bungo already told you, but we made friends (without initially realizing it) with Harntranft's great-granddaughter (her father was the son of his daughter) at the conference. She & her husband were really sweet. They still have a bunch of his stuff, too (including some coats! and the letter from Annie Surratt later thanking him) but a lot of his stuff is in the Penn State Archives (as you prolly knew). Anyway, we thought of you. And tried to refer to him by his proper name ^^. If you ever want to contact them for any reason we picked up their email & address with the warning that we might pass them along.
