Thomas Dongan (c.1590–1663) was an Irish judge of the seventeenth century. His career was dogged by accusations of recusancy and of disloyalty to the English Crown. He is chiefly remembered as the father of Margaret Dongan, wife of the Dutch scholar Arnold Boate, who commemorated her lovingly in his book The Character of a Truly Virtuous and Pious Woman, and also wrote with affection and respect about her father.[1]
