Paris Precinct J.N. MARSH,1 farmer; P.O. Paris; born in this precinct March 26, 1845, the eldest son of Benedict Beal Marsh, born in this precinct 1808, who was the youngest son of Beal Marsh and Eleanor Corbin, who were natives of Maryland. This ancient couple settled here in Bourbon County, in the latter part of the last century.  His settlement was near Paris, on the farm now owned by his grandson, B.B.  Six children were born to Benedict B., the eldest was Dryden, who was born 1798; then Abram C., Nicholas C., Thomas K., Rachel and Benedict B.; all lived to be grown.  The parents of the above died as follows: Beal, Nov. 5, 1835, his wife Eleanor, May 19, 1810. The father of Nicholas, our subject, was raised on the farm, but this not being satisfactory to him as a business, he went to Philadelphia where he learned the trade of silversmith, which he followed several years at Flemingsburg; then went to Richmond, this State; afterwards removed to Paris, where he associated with his brother, Thomas K., in the same business, which continued for several years; he finally located on the homestead owned and settled by his father.  He then engaged in farming and continued until his retirement from business.  His death occurred 1875, his wife, four years later.  Four children were born them, viz : J. Nicholas, Beal G., Thomas K. and Benedict B., also one daughter, who died aged fifteen. Nicholas, whose name leads this page, was married May 22, 1866, to Anna Steele, born in St. Louis, Mo., daughter of Dr. William Steele; a native of Bourbon County.  Soon after the marriage he removed to the farm he now owns, which is located on the Maysville Pike.  His farm consists of 384 acres, and well improved, having excellent buildings thereon.  He is engaged in the breeding and raising of short horn cattle and Cotswold sheep. Six children have been born to him, whose names are, Eleanor R., Thomas K., Martha D., Benedict B., William C., Anna F.
