Duck Dynasty stars: Si Robertson

Si Merritt “Si” Robertson is Duck Commander Phil’s younger brother, best friend, and partner in crime.

Born on April 27, 1948, Si Robertson has a very specific job at the Duck Commander workshop, fashioning the reeds that are inserted in every patented duck call. It’s a pretty easy job, made needlessly difficult by the fact that Si Robertson can never seem to stay on task.

A Vietnam War veteran, Uncle Si Robertson often shares his war stories with the guys in reality show Duck Dynasty, which usually gets the crew behind schedule, much to his nephew Willie’s dismay.

Si Robertson’s most famous story is that while serving overseas, his mother sent him a blue mug. Thirty years later it’s still hanging from his back pocket and he continues to only drink from this cup, every day.

Uncle Si is married to Christine for many many years and they have together two children: a daughter, Trasa Cobern Robertson, and a son, Scott Robertson. Christine, Trasa and Scott are not featured in the reality show.
