SMALES is a relatively uncommon surname in the U.S.: only 43 registered in the World War I draft (and none named Joseph). Of these, one caught my eye:
Harold SMALES, 30, born June 14, 1886
in Sydney, New South Wales, Australia
on June 05, 1917 living at 449 13th Avenue, Long Island City, New York
bricklayer - married, with three children
registered in Queens County, New York
Any possibility of a long-ago connection?
