Cy and Jack Ferry played major league baseball around the turn of the 20th century and thus were among some of the earliest sets of brothers to appear in the big leagues.
Neither had extensive major league careers, although minor league baseball extended their playing careers.
Jack played four seasons with the Pittsburgh Pirates, where he was a teammate of the great shortstop, Honus Wagner.
Cy played only two seasons in the majors, one of them with the Cleveland Naps were he was a teammate of future Hall of Famer Nap Lajoie.
