Interesting observation that Pawnee Killer's father-in-law, Little Bald Eagle, could have been a Sichangu Lakota.
That would explain in part or fully that some Sichangu lodges were sometimes mentioned as camping with Pawnee Killer.
In 1896, a group of 89 Sichangu people were invited to Cincinnati, Ohio to participate in a Wild West Show.
In June 1896, the Sichangu group arrived in Cincinnati by a train with their lodges and horses.
The Sichangu group camped in Cincinnati for 3 months.
The Sichangu group was a mixture of men, women and children, i.e. families
If we allow 4-7 persons per family or lodge, it means ca. 13-22 Sichangu lodges or families camped in Cincinnati, Ohio during the summer 1896.
Like often/always, you suspect that these families were related.
Among these 89 Sichangu people, were at least 2 sons of Iron Shell, i.e. Young Iron Shell and Goes to War.
There was also a person identified as Little Bald Eagle.
I wonder if Little Bald Eagle was related to Iron Shell's family.
Below are links to 2 PDF-files by Susan Labry Meyn about this 1896 visit of the Sichangu familes to Cincinnati, Ohio.

www.ohioswallow.com/extras/9780821417393_intro.pdfIn both of these PDF-files by Meyn, are photos of a person identified as Little Bald Eagle.
In [1] on page 37.
In [2] Figure 9 on page 35,
Little Bald Eagle in these 2 PDF-files by Meyn is obviously the same person.
But Little Bald Eagle in these PDF-files by Meyn, does not look alike Little Bald Eagle who is supposedly on the photo above in the first post of this thread.
It might be because of a different age of the same person or the Meyn's Little Bald Eagle is a son of older Little Bald Eagle.
I am not sure when the above group photo in the first post in this thread was taken.
But the photos in the 2 PDF-files by Meyn were taken in 1896.
