Because of the extensive research by and publications of Frederick Lewis Weiss for the Society of the Descendants of the Colonial Clergy, brief biographical information about clergy ordained in the original 13 colonies prior to July 4, 1776, is easily available.
See sample entries.
Those clergy who were graduates of Harvard College have biographical sketches in the series Sibley's Harvard Graduates (latest volume through 1774) [Ref. LD2139.S5], and clergy who were graduates of Yale College have biographical sketches in the series Yale Biographies and Annals (last volume through 1815) [Ref. LD6323.D5].
Some of these clergy also have printed biographies and/or autobiographies. Browse HOLLIS Classic under subject with last name first for the author and title of books about them. If you are not a Harvard library patron, search your own catalog for these works about them. If the book is not available locally, consider an interlibrary loan request.
