James Warren was a man of great influence and wealth and a Justice of the Peace at Plymouth. He is frequently called Captain James Warren on the records. He was a man of enterprise and judgement, and became a very large landholder in the town and vicinity. He bought the entire real estate of Edward Doty, his father-in-law, as the heirs became of age or removed from the town. His name is identified with the history of Plymouth by his various transactions and public-spirtited improvements in the building of the town, and by connection with the distinguished families of the vicinity.
