I Stand Corrected By Too Moons and Barenstein

Two moons was one of the models
for the  Buffalo nickel

Note the following in regards to a notable person recently added to Wikipedia’s Deaths in 2026 site: 

Rhett Bernstein (September 10, 1987 – July 7, 2026) 38, American soccer player

The  Mandela effect: 

The Berenstain Bears being spelled "Berenstein"

In late 2002, an exhibit titled "The Berenstain Bears Celebrate: The Art of Stan and Jan Berenstain" opened at the James A. Michener Art Museum in the Berenstains' home of Bucks County, Pennsylvania. Organized by the Norman Rockwell Museum in Stockbridge, Massachusetts

James Albert Michener (February 3, 1907 – October 16, 1997)

 Norman Percevel Rockwell (February 3, 1894 – November 8, 1978)

A “February 3(x2)” pattern cluster.   

So venturing to the February 3 wiki page and using the formula we arrive at: 

• 1777 – John Cheyne, Scottish physician and author (died 1836)
• John Cheyne (3 February 1777 – 31 January 1836) 

Cheyne is both a surname of Scottish origin which means "oak tree",  AND the name is similar enough to the  Cheyenne , note from the tribe’s wikipedia page: 

Two Moons, Northern Cheyenne Chief, in Cheyenne: Éše'he Ȯhnéšesėstse, also known as Ónonevóo'xénéhe (Ree Roman Nose) or Mȧsėhávoo'xénéhe (Crazy Roman Nose)

Two Moons (c. 1847–1917), or Ishaynishus (Cheyenne: Éše'he Ôhnéšesêstse),^[1] was one of the Cheyenne chiefs who took part in the Battle of the Little Bighorn and other battles against the United States Army.

As for standing to be corrected, note my US Dead Heads (Part 4: Iron Tail), … in fact there were 3 chiefs used as models for the Buffalo nickel. 

• Chief Iron Tail (Oglala Lakota / Sioux)
• Chief Two Moons (Cheyenne)
• Chief John Big Tree (Seneca)
