A Wikipedia discovery, entry for Adam Smith (note 1):

In his fourth year, while on a visit to his grandfather’s house at Strathendry on the banks of the Leven, [Smith] was stolen by a passing band of gypsies, and for a time could not be found. But presently a gentleman arrived who had met a gypsy woman a few miles down the road carrying a child that was crying piteously. Scouts were immediately dispatched in the direction indicated, and they came upon the woman in Leslie wood. As soon as she saw them she threw her burden down and escaped, and the child was brought back to his mother. [Smith] would have made, I fear, a poor gypsy. (John Rae, Life of Adam Smith,  [1895])
