Smith, an authority on the subject, estimates that 'not less than a half, nor more than two-thirds, of all white immigrants to the colonies were indentured servants or redemptioners or convicts,' and that, beginning in 1728, 'by far the greatest number of servants and redemptioners' came from Ireland. It would seem, therefore, that more than one hundred thousand Scotch-Irish came to America as indentured servants. "
