I am interested in any information you may have regarding Samuel H. Rowswell. He was a Great Lakes laker Captain and a cousin of my grandfather, Samuel Benjamin Chaffey, who was born April 19, 1878 in Walkerton, Ontario, Canada. My father, Samuel Benjamin Chaffey Jr., sailed on at least two Ships under Captain Rowswell;the Frank Billings and C.L. Hutchinson,in 1937. Also, how may I obtain a copy of your book, Hub of the Rideau?
