A descendant of the hardy souls who founded Quebec and New York City, settled much of Canada and New England, and one adventurous ancestor who was blown off course and accidentally discovered French Guiana, Geoff still makes an annual pilgrimage to Mt. Desert Island, where his family has summered off and on since 1603. An expert on the Jesuit missions of Chiquitos, he has published more works in English on the region than anyone alive, and his writings, photography, and website on the same have won considerable international acclaim.
