On a different subject, I think I have only seen mentioned, as to church affiliation, that he was a clerk in the Presbyterian. I recently noticed on his Find-A-Grave memorial what purports to be a transcription from his tombstone at the Bethel United Methodist Church Cemetery in Charleston, South Carolina.
“A native of Massachusetts / He served the church as a ____Preacher during the five last years of his life / with much acceptability / And died in full assurance / of a blessed immortality Oct 20, 1812 Aged 40 /”
Unfortunately, there is a missing word that might say “Methodist Preacher,” “Lay Preacher,” or any number of things. However, based on a few newspaper mentions I could find, I believe it is correct that he was a preacher later in life, and probably a Methodist. One advertisement in The Charleston Mercury in 1828 for The Sacred Songster says, “Being a Collection of Hymns and Spiritual Songs for the use of Religious Assemblies, but more particularly of the Methodist denomination, by Amos Pilsbury, author of the United States Sacred Harmony.”
Then there is an announcement of his daughter’s marriage in 1830 that calls him “Rev. Amos Pilsbury.”
“MARRIED, on Sunday evening last, by the Rev. Mr. Brown, Mr. ALEXANDER CRAFTS MACKAY, to Mrs. ANNESS C. O. REYNOLDS, daughter of the late Rev. Amos Pilsbury.”
Also in “Biographical Notice of William Pilsbury, A. B.” in Boston Observer and Religious Intelligencer (January 22, 1835, p. 26) there is this note that also suggests Amos Pilsbury was a Methodist minister:
“* The widow of the late Rev. Amos Pilsbury, later brother of William Pilsbury. This lady resides in Columbia, S. C., but was in Charleston on a visit, where the writer providentially met her, who conducted him to the place of interest; which is the Methodist burying ground in the westerly part of the city, near the monument, erected by the young men of the Methodist society to commemorate the virtues of their deceased ministers.”
If this is not commonly known, I thought it might add a little more breadth to the biographical information on Amos Pilsbury.
