Edwin Greble

There are only six items in the Edwin Greble collection, but one extraordinary quillbox. Autry Object ID: 5.G.22

There is no relevant information about Greble in Michigan. The only possible connection is that Greble was a lifelong military man and "served as an aide to Oliver Otis Howard from 1885 to 1889.” 

Another possibility is that if this is Boyd’s, she gave it to one of these men when she travelled to Washington DC 

Oliver Otis Howard had Military commands and Native American affairs[edit] 

In 1872, Howard, accompanied by 1st Lt Joseph A. Sladen, who served as his aide, was ordered to Arizona to negotiate a peace treaty with Cochise, resulting in a treaty on October 12, 1872.[16] 

He was placed in command of the Department of the Columbia in 1874, went west to Washington Territory's Fort Vancouver, where he fought in the Indian Wars, particularly against the Nez Perce, with the resultant surrender of Chief Joseph. He was criticized by Chief Joseph as precipitating the war by trying to rush the Nez Perce to a smaller reservation, with no advance notice, no discussion, and no time to prepare. Joseph said, "If General Howard had given me plenty of time to gather up my stock and treated Too-hool-hool-suit as a man should be treated, there would have been no war." 

Subsequently, Howard was superintendent of the United States Military Academy at West Point in 1881–82. He served as commander of the Department of the Platte from 1882 to 1886 and the Military Division of the Pacific from 1886 to 1888. From 1888, his final command was of the Department of the East (Military Division of the Atlantic) at Fort Columbus on Governors Island in New York Harbor, encompassing the states east of the Mississippi River. He retired from the United States Army at that posting in 1894 with the rank of major general. The French government made him a chevalier of the Legion of Honor in 1884 and he was subsequently promoted to the ranks of officer and commander.[17]
