Published sermons on the deaths of four more ministers

Wallin published other funeral sermons besides that for John MacGowan near the end of his life, including for these other ministers

In 1753 a sermon on the death of Jonas Thorowgood (1668-1753). It was Thorowgood's medical knowledge that helped Wallin with his lameness as a young man. The funeral was at Little Parndon, Essex, near Harlow, where Thorowgood had been pastor since 1717 (having served previously as assistant and joint-pastor with John Wilson).

In 1762, on the death of John Auther (1688-1762) poet and pastor, the first Baptist minister at Waltham Abbey, Essex, from 1729.

In 1772 there was a sermon for  John Gill (1697-1771).

In 1773, one for Samuel James (1716-1773) author and pastor in Hitchin. James, a son of the manse, was born in Curborough near Litchfield. He had a Welsh father (Dr Philip James 1664-1748) who was a minister for over thirty years in Hemel Hempstead. James's mother, Anna, was the youngest child of Lawrence Spooner (1700-1764). His childhood classics teacher was Daniel Turner (1710-1798). After ministerial preparation, James served from the early 1740s in Hitchin, also in Hertfordshire, at the end of the life and ministry of John Needham. (Needham was involved in Wallin's education as a boy). In 1744, he married Needham's daughter, Mary. At the beginning of 1748 he began to preach systematically through the New Testament on Sunday mornings. As over the years he came nearer to the Book of Revelation, he was apprehensive, but the Lord took him before he was able to begin expounding that difficult book.
