Henry Ainsworth, an English nonconformist divine, the date and place of whose birth are unknown, died in Amsterdam in 1622. In 1590 he attached himself to the Brownist sect, and was afterward compelled by persecution to fly to Holland, where, in connection with a Mr. Johnson, he established a church at Amsterdam. He was a good Hebrew scholar, and published annotations on the Psalms and Pentateuch, together with a literal translation of the latter, a translation of Solomon's Song, and other works of a somewdiat similar character.
