1860, according to his brother's son Lone Bull jr, he had a reputation as a "great raider". For a story involving him in battle with the Pawnees, see Luther Standing Bear MY PEOPLE THE SIOUX p.
He owned about 120 horses, probably the largest herd among the Southern Oglalas. According to Jack Ewers's informants owning 100 horses marked a very rich man: as comparison, we know that Old Man Afraid of His Horse in 1875 owned 100. He had a very large tipi made of twenty buffalo skins, which he gave away to his sister Eagle Come Out. He then lived in another large tipi of 16 skins. In this era a tipi of 14 hides was considered large.So, a very prosperous man. By the 1860s Broken Arm was the nominal headman of the family, and represented it in the Kiyaksa band council. His'brother' Slow Dog (son of one of his mother's sisters) was another such headman.
Since he visited among the Southern Cheyennes, and was present at the Battle of the Washita, I suspect that his mother belonged to Black Kettle's Wutapiu band of Cheyennes (a band of hybrid Cheyenne-Lakota origin). Note that she was one of three Cheyenne sisters all born in the early 1800s, who each married into the Oglala. Another sister was the mother of Slow Dog born c. 1826, and another Kiyaksa-hcka headman-counsellor, and the third was the mother of High Bear born c. 1840, identified with the Skokpa sub-band of the Kiyaksa, and one of the Southern Oglala head akichita.So Slow Dog, High Bear, and Broken Arm (and his biological brothers), all called each other brother. The frame measures 14.75 tall by 12.75 wide, and the actual photo measures 8.75 tall by 7 wide. Minor aging to the photo as expected with age. There is one small area (a few millimeters in size) on the bottom of the photo where the black and white has faded/is missing.
