The only "Captain" Hoxie I know of was John Hoxie, a Texas Ranger probably born about this time. (??) Captain is a rank in the Texas Rangers. Family history says he went to Nome, Alaska (from Texas?) during the Yukon gold rush and owned a saloon with Wyatt Earp (1898?)
My mother (Doris Pomeroy - mother was Florida Hoxie whose father was C.D. Hoxie of Concord, MI) said he was her Great-uncle. I also think he was the one that she said called all of his dogs "Captain"; maybe because of his being a Ranger??
His being a Ranger was documented in a book I read as a cchild about the Hoxies. It was a family tree in book form. It started with Ludwig Hoxie in Sandwich, MA in 1643. Ludwig came from Holland, but I think he sailed from tthere and was English or scottish living there (a Separatist/Pligrim) or that was taken from a ships log. Sometimes ships sailed from England and stopped in Holland before crossing the Atlantic (for provisions, trade goods, passengers??).
I read a blog here that said the name came from Hawk's eye (eye pronounced long E; means island in ancient celtic, like Chelsea meaning Chells eye - SEE: the novel "London" by Edward Rutherford).
Hope this helps.
