FRON HISTORY OF WASHINGTON COUNTY, PENNSYLVANIA
When eighteen years of age he left his father's house, which was then in Bedford County, and came to "Redstone Old Fort." The first work which he performed after coming to Fayette County was in the boat-yard of Joseph Allen, at the mouth of Little Redstone Creek. He developed a fondness and an aptness for boat-building, and after remaining with Mr. Allen one summer was employed as foreman in the yard of Robert Rogers, of Brownsville, for whom he built the first flat-bottomed boat launched west of the Alleghenies. The superiority of this boat over others then in use was manifest, as was also Mr. Pringle's ability as a boat-builder, and orders for vessels like unto this one were so numerous that he determined to embark in business for himself. He began in the yard at Brownsville, and remained there until 1844, when he purchased the Ephraim Blaine property in West Brownsville, and upon it graded and established a boat-yard, which he operated until 1879, when, incapacitated by old age and disease, he transferred his business interests to the care of his son, John D. S. Pringle, and his son-in-law, Andrew C. Axton, both of whom are noted for their energy and business ability.
Mr. Pringle is a courteous, hospitable gentleman, and his life has been honest, busy, and useful. He has long been a member of the Cumberland Presbyterian Church, to whose benevolent enterprises he is a liberal contributor. He started in life with a sound and vigorous constitution, and, being temperate in his habits, he preserved a hale and healthful body more than threescore and ten years. He is respected by his neighbors, esteemed by his friends, and sincerely loved by his family.

He was married May 3, 1832, to Elizabeth P. Horner, who died Nov. 29, 1844. By this marriage there were six children,--Elizabeth, who married Jacob Walter, is dead; Ann is unmarried, and resides with her father; William H. was a soldier in the late war, and died of disease contracted in a Southern prison; George W. died when a young man; Sarah is the wife of Andrew C. Axton, who served as a soldier in the late war, enlisting in the old Washington Cavalry, which after eighteen months' was incorporated in the Twenty-second Pennsylvania Cavalry. His maimed body bears witness that he loves and has served his country well. Mary died in infancy.

Mr. Pringle was married to his present wife, Sarah Ellen Snider, Oct. 16, 1845. They have ten children, all living. They are John D. S., who did good service in the war of the Rebellion as a member of Company F, Eighteenth Pennsylvania Cavalry, married Cornelia Deems; David S., married Nancy J. Gamble; Nancy, married Newton McClaine; Ella, married William H. Harrison; Mary, married John W. Thompson; Simon P., married Margaret Moorehouse; Christian S. and Andrew A. are unmarried.

Politically Mr. Pringle was originally a Democrat. He continued in that faith until the organization of the Republican party, since which time he has acted with it. His business life in this vicinity extends over a period of more than half a century, and in that time he has launched over five hundred boats upon the Monongahela. The largest one in that number was the "Illinois." She was three hundred and four feet long, had a fifty-two-foot beam, and was seventy-five feet across her deck.
