He was born on October 3, 1946, in Canton, Illinois, to James Hobart and Marian Ruth (Taylor) Lock. On March 21, 1970, he married Cherie Ann Finch in Atwater, California. She survives.

Terry was a 1964 graduate of Avon High School. He went on to attend the University of Illinois, where he earned a bachelor’s degree in Agricultural Mechanization. Following his education, he proudly served his country in the United States Air Force from 1968 to 1975 as a navigator in the RF-4.
Throughout his professional career, Terry worked in banking, where he was respected for his knowledge, integrity, and dedication. Yet, despite his success in the financial world, farming was always where his heart truly belonged. He cherished the land, valued hard work, and found great fulfillment in the agricultural way of life. Terry was known for his quiet strength, practical wisdom, and unwavering devotion to his family. His greatest joy came from spending time with those he loved, especially his children and grandchildren.
