The 1890 Pine Ridge census lists the family of White Eyes as belonging to the Iwayusota band of Oglalas, Medicine Root District. Iwayusota (translated as Used Up by the Mouth, or Used Up by Begging) was a sub-group of the Kiyaksa (or Kiyuksa), i.e. the Southern Oglalas whose hunting grounds had traditionally been south of the Platte River in sw. Nebraska and neighboring sections of Kansas and Colorado.
Anyway, here is the family as listed in the 1890 census.
White Eyes, Father, age 65 (born ca. 1825)
Assiniboine, wife of White Eyes, age 65
Jacob, son, age 21, born 1869
Pretends to run, grandson, age 12
Small Fish, grandson, age 10
Turns Around, grandson, age 7.
The 1892 Pine Ridge census lists the family as follows:
White Eyes, age 67
Old Woman, wife, age 63
Sword Red Fish, grandson, age 13
Frank Little Thunder, grandson, age 14.
Jacob is not listed. I presume Sword Red Fish (Lakota name given as Hohan Luta) is equivalent to Small Fish of 1890, and that Frank Little Thunder is Pretends to run of 1890.
I don't know about the Cheyenne connection, but White Eyes the elder is said to have been a son of Little Thunder, the Brule chief. In 1868 he was photographed by Alexander Gardner at Ft Laramie as part of a group including Spotted Tail. That same year he was part of the group that went from the Upper Platte Agency, then located at North Platte, Nebraska, to the the new Whetstone Agency on the Missouri. Interestingly he was then listed as an Oglala leader. In 1872 White Eyes went to Washington as part of the Brule delegation led by Spotted Tail. Again, Gardner made portraits of the delegation including White Eyes. Maybe Dietmar could post these pictures up.
I am interested in all these families, and I was interested to read your mention of Millicent, daughter of Fast Whirlwind, being married to Elbridge Gerry. Is she the same woman sometimes called Millicent Red Kettle? And if so, do we know what the relationship was between Fast Whirlwind and the Red Kettle family? Fast Whirlwind was the chief met by Francis Parkman in 1846 and called simply The Whirlwind. He was the leading chief of the Southern Oglalas in the 1840s, after the death of Bull Bear.
I hope this helps, and looking forward to your updates
