The age of historic structures is often a question of great interest to historians, restoration architects, and home owners. Tree-ring dating of wood and house timbers can yield precise dates on the construction of historic structures, additions, and changes in architectural styles. We have dated over 40 historic structures in Missouri, Illinois, and Ontario such as the Nathan Boone Home (Ash Grove, Mo.), the Perrie Menard House (Kaskaskia, Ill.), and the DeLasuss House (St. Genevieve, Mo.).Usually timbers must be made of a long-lived tree species such as oak, pine, or cedar and have atleast one hundred rings or more to be dateable.
