He had the respect and the affectionate regard of all his brethren in the ministry. They looked upon him as one of the best, and in some respects, as one of the most gifted among them. While he was not popular as a preacher, he was yet an able and excellent sermonizer. He had great strength and fertility of mind, and many of his written discourses are marked by decided intellectual superiority. He was an evangelical preacher. He preached plain truth. He dwelt much on the great cardinal doctrines of the Bible, apportioning them and applying them with wisdom and with unction. He was not left without witness. The leaven of his influence was felt, and is still felt for good in this church. Its growth and prosperity are (under God), due in some considerable measure to his labors."

During the ministry of Mr. Marshall, unfortunate dissensions sprung up in the church, which resulted, in 1841, in the withdrawal of nine members, who, together with two members from the second Congregational church of New London, Conn., were organized into a church on Nov. 17th, 1 841, by the Presbytery of North River, and became the second Presbyterian church of Peekskill, in connection with the New School assembly. They began public worship on Sunday, Nov. 21st, 1841, in the old Methodist church on South street. Services were conducted by the Rev. Daniel Brown. Within a few years a church edifice was erected and was dedicated on April 9th, 1845. In 1870, the building was enlarged and rebuilt.
