I don't have an actual copy of the obit but the text was taken from the Dansville Express, 27 Feb 1879, p3 and goes as follows:
"CAPT. DAVID C. PORTER
Death of another Soldier of the War of 1812 and the Last Survivor who Witnessed the Blowing Up of Fort Erie.
Another old soldier of this section --Cap. David C. Porter, living in the Poag's Hole Valley -- was "mustered out of the service", last Friday, and his funeral took place from the English Lutheran church on Monday, Rev. P.A. Strobel officiating.
Capt. Porter was born near Trenton, NJ., Feb 14,1789. He was a brother to Matthew Porter who came to Dansville in the winter of 1796, making his way through a deep snow from Bath and guided only by marked trees. In the summer following, David came to Dansville and has resided here ever since.
In the spring of 1814 he volunteered in the service of the United States in the war which we were then waging against Great Britain, serving as a First Lieutenant under Captain John Kennedy of Bath, in Col. Hopkins' regiment of volunteers. He participated in the battle before Fort Erie which was fought on the 16th Sept., 1814, assuming command of the company, in consequence of Capt. Kennedy having been disabled by a wound early in the engagement. Capt. Porter witnessed the blowing up of Fort Erie by which nearly three thousand British soldiers were destroyed, and it was said of him before his death that he was the sole surviving witness of that event.
In early life he married Miss Noe but never had any children. All through life he was noted for his energetic, enterprising spirit, was a man of genial manners, a worthy citizen, a true patriot and a man of correct moral habits. Of late years he had led a retired life, hardly ever appearing in the village except on Independence Day, when he was selected with other veterans to occupy a post of honor in celebrating the day.
While he lived he commanded the respect of all and his death will be truly lamented."
The obit can be found in the Dansville Public Library, Dansville, New York
My line is through David's brother John. John would be my 6th Great-grandfather. I would be happy to share any information I have on the family.
