with his descendants, passing from Weeks to his daughter Caroline F. Weeks Griffin, who passed them to her son, Leslie Griffin. In 1948 two Mormon missionaries, Frank Gifford and Vern Thacker, contacted Griffin while tracting door to door in Boron, California. Griffin and the two missionaries became friends, and, when Griffin learned that Thacker was returning to Salt Lake City, he gave him Weeks' drawings to donate to the LDS Church. Thacker did as Griffin requested, and Weeks' original drawings proved invaluable in the later reconstruction of the Nauvoo Illinois Temple. Other works The Isaac Chase Mill, designed by Weeks and built in 1852, now part of Liberty Park, 6th East Salt Lake City, UT, is listed on the U.S. National Register of Historic Places.
