MANSON, WALTER. (Scotland, 1808--Dubuque, IA, Mar. 28, 1879) At about the age of twenty-two, Manson immigrated to Canada. He then moved to Vermont, Ohio, and finally Dubuque County, Iowa. He was involved in milling with James Pratt and Thomas Watters, Sr.
Manson bought the ROCKDALE MILL and managed the business until 1868. He then sold the property and spent the remainder of his life building business blocks and residences and looking after his investments.
