Duck Dynasty’s Si Robertson celebrates his 67th birthday on Monday, April 27th.
Silas Merritt Robertson is Phil’s youngest brother, a Vietnam War veteran, and preacher.
Si Robertson is kind of like the Kramer of Duck Dynasty. He is known for his storytelling, his constant use of the phrase “Hey, Jack!” and his ever-present blue plastic cup, which his mother sent him while he was stationed in Vietnam.
He is often filmed carrying around a jug of sweet tea and he loves pizza.
Si Robertson married his longtime girlfriend Christine Raney (who is not featured on Duck Dynasty) in 1971. They have two children together – Trasa Cobern and Scott Merritt Robertson – and eight grandkids.
