Posted my biography of Capt Andrew Hague Parr.
I also want to point you to the page The People of Georgetown. It explains the relationship between Andrew H Parr and the Calhoon and Ebert families.
Recently I discovered a book in my mother’s library, “Massacres of the Mountains: A History of the Indian Wars of the Far West, 1815-1875” by JP Dunn Jr. It was originally published in 1886. My version was published on 1 Jan 1965. I have not read the entire book – only the introduction and the chapter on the Blackfeet Nation entitled “Punishing the Piegans”.
The account is sympathetic to the Indians. It is an alternative point of view of a man who lived at the time of the events. Massacres is written in the manner of Howard Zinn.
My prime interest is in the state of Indian affairs in the Montana Territory around 1869, the season my 2nd great grandmother compiled her journal. I have summarized that chapter of the book on a page named Blackfeet Nation in 1869.
