Obadiah Bruen Brown was born in Newark, New Jersey, on July 20, 1779, the son of Mary Bruen Brown and Eleazar Brown. Raised a Presbyterian, Brown started attending the Baptist Church when it was organized in Newark. At age 24, he joined this church and soon the members of the congregation began encouraging him to enter the ministry. Within a few months, O.B. Brown had gone to Scotch Plains, New Jersey, to study theology with the Rev. William Van Horn, pastor of the most prominent Baptist church in the New Jersey-New York area.
