Herman Junior Rock better known as Jim, was born in Pierson, Iowa on September 8th, 1940. His parents were Herman and Ethel (Glover) Rock. He lived his entire life in Pierson and graduated from Pierson High School. He married the love of his life, Darla (Bennar) Rock on May 3rd, 1959. They married while Darla was still in high school at the Kingsley Methodist Church because Jim was shipping out to the Navy and they wanted to be married before he left. He served in the Navy beginning in May 1959. They have lived on the Rock Century Farm near Pierson for 65 years.

Jim was involved in farming his entire life, sold insurance and worked 27 years at the Farmers Savings Bank in Pierson. He furthered his education by getting a Graduate Degree from the University of Wisconsin Graduate School of Banking. He was an active member of the Pierson United Methodist church since his youth. Jim and Darla served as youth leaders for the church for many years. He enjoyed fishing, traveling, and an occasional Busch Light with friends. If you were lucky enough to imbibe with him, you probably heard him tell a funny story or two. He may have even repeated a story once in a while.

All the family members want to thank you for being part of Jim’s life. As you know, he was a fun-loving guy, and we will all miss him. We’re pretty sure that he’s holding a Bible, a Busch Light, and a fishing pole on the perfect catfishing stream.
