Le Mercier dedicated his book, on Detraction, to his people. Therein he says, "You have not despised my youth, when I first came among you; you have since excused my infirmities; and, as I did the same, in respect to yours, it has pleased our Saviour, the head of his church, to favor us with an uninterrupted peace and union in our church, for the almost eighteen years that I have preached the word of salvation to you." His book was published in 1733. He therefore became their pastor between 1715, when Daillé died, and 1716. He died March 31, 1764, aged 71. He was therefore born in 1693, and ordained about the age of 22. Le Mercier's will is dated, at Dorchester, Nov. 7, 1761. A codicil was added, at Boston, Feb. 3, 1764. He left his estate to his four children, "_Andrew, Margaret, Jane, and my son Bartholomew, if living_." He enjoins upon his heirs the payment of Bartholomew's debt to Thomas Hancock, for which he had become responsible, and which he had partly paid. By his will, he appointed Jane and Margaret to execute his will. In the codicil, he refers to the disordered state of Margaret's mind, and appoints Zachariah Johonnot, in her stead, requesting him to be her guardian. The whole estate was appraised at £232. 18. 6. sterling. Years rolled on: juxtaposition and intermarriage were Americanising these Huguenots, from month to month; and, ere long, they felt, less and less, the necessity of any separate place of worship. On the 7th of May, 1748, "Stephen Boutineau, the only surviving elder," and others, among whom we recognize the Huguenot names of Johonnot, Packinett, Boudoin, and Sigourney, conveyed their church and land to Thomas Fillebrown, Thomas Handyside Peck, and others, trustees for the "new congregational church, whereof Mr. Andrew Croswell is pastor." After a while, this church became the property of the Roman Catholics; and mass was first celebrated there, Nov. 2, 1788. The Catholics, in 1803, having removed to Franklin Place, the old Huguenot church was taken down; and, upon the site of it, a temple was erected, by the Universalists; showing incontrovertibly, thank God, that the soil was most happily adapted to toleration.
