Hi, Marci,
These families coming from Roxborough Scotland in the 1850s to Ireland and Canada seem to be only distantly related to us, probably from before 1670.
James is a pretty common name amongst Scots and Scots-Irish. For example, John Cranston and Mary Moore had an eldest son named James (born Monaghan, Ireland, 1785 -- we're descended from his younger brother Thomas). Probably James was also John Cranston's father's name, too (based on the Scots naming rule).
