Our lineage continues through John Miller Thomson, also known as Jack Thomson. He graduated from Miami Senior High School in 1949, attended the University of Florida and the University of Miami, graduating with a B.B.A. degree in accounting in 1953. That same year, he married New York transplant, Dorothy June Hayward (b. June 24, 1932 in Shrub Oak, New York) on November 29, 1953. Shortly after the ceremony, he was drafted into the army and served until January, 1956, primarily at Forth Jackson, South Carolina, with the 101st Airborne Division Headquarters Company. After discharge from the service, he returned to the University of Miami on the GI Bill, where he graduated from law school in February, 1959 with a LLB degree, later converted to a JD degree.
Jack had planned to practice law in Havana, Cuba, but Castro cut this opportunity short. After practicing law in Miami with his father under the firm name, Thomson & Thomson, he went on to other law firms in South Florida including those of Charles Papy, Jr. and Holiday & Gardner, and worked as General Counsel at various real estate investment firms including Meridian Housing and Development Company and Newport Development Company. He then went on to form the law firm, Tobin & Thomson in 1976, and for the next fifteen-years concentrated on personal injury litigation while continuing in real estate practice and learning real estate planning, probate and trusts. Since 1991, he has been a solo practitioner in the real estate and estate planning specialties.
