Alpha Washtenaw Bryan (Feb. 27, 1824 - ??) was so named by John Allen and Elisah Rumsey for being the first white child born in Washtenaw County. The son of John and Sarah Bryan, among the first white settlers of Washtenaw along with Woodruff and Cross, Alpha was born a mere four months after his parents' arrival by ox cart in Woodruff's Grove on October 23, 1823.

Alpha and Sarah were guests of honor at Washtenaw County's 1874 semi-centennial celebration. At that time, Alpha was a schoolteacher in Tennessee; Sarah was a resident of Constantine, MI, just south of Battle Creek.
