Williamson, C. D. (Carlyle Dougan), 1886-1959.

Carlyle Dougan Williamson (1886-1959) was born in Leadville, Colorado, and became a cashier at Carbon State Bank in Hanna, Wyoming in 1909 and later was president from 1930 to 1955. The bank was reorganized into the First National Bank of Hanna in 1920 and again in 1927 to the Hanna State & Savings Bank.

In 1916 Williamson became affiliated with P.J. Quealy, the receiver of the Carbon Timber Company which conducted logging and tie cutting operations in Carbon and Albany Counties, Wyoming, and was often Wyoming's sole producer of ties for the Union Pacific Railroad. Williamson and Quealy reorganized the company into the Wyoming Timber Company, with Williamson serving as president. He was also closely associated with the Quealy Land and Livestock Company, which was also owned by Quealy, and helped to found the Intermountain Telephone Company of Hanna in 1912. The Wyoming Timber Company also held interest in the Wyoming Timber Lands Company and the Megeath Coal Company, both of Hanna, Wyoming.
