Angelique Chengelis has an article in today's Detroit News regarding the kinship of Courtney Avery and Michigan legend George Jewett.

I'd been ignorant of Jewett's legacy until I saw an article in March's Michigan Today. The article (http://michigantoday.umich.edu/story.php?id=8143) is well worth your time to read, as Jewett's legacy is impressive. Michigan would not have another african-american player until the legendary Willis Ward. I cannot recommend the article highly enough if you're unaware of Jewett's story.
Jewett's father was an Ann Arbor blacksmith. Not only was Jewett Michigan's (and the B1G's) first african-american player (1890!), but he was a renaissance man and powerful business presence in Ann Arbor after graduation. He was also Ann Arbor High School's 1889 valedictorian. He played for the Wolverines in 1890 and 1892, later transferring to Northwestern to become their first african-american player too. (The transfer was motivated, according to Wikipedia, due to a dispute with Michigan's Medical School dean.)
Per Chengelis, Avery did not know of his relationship to Jewett until he arrived on campus. It's a wonderful bit of history, and with all the talk of "Legacy" jerseys I doubt Avery would trade his legacy for any teammate's.
