After the War of 1812, Josiah O. Watson and his brother John Brown Watson inherited their father's plantation in Johnston County on the Neuse River in 1815. He bought his brother's portion and accumulated many plantations during his life. When he died in 1852, he owned approximately of land in Johnston and Wake Counties. The main plantation was called Pineville and was located across the Neuse River from Clayton, NC, where North Carolina Highway 42 intersects Buffalo Road. After his death, most of the plantation was inherited by his nephew J. W. B. Watson, who controlled it until his death in 1897. At that time, much of the land was divided among many heirs and the main plantation and house was eventually sold to the Percy Flowers family. Currently, much of the land is being developed into a residential community called Flowers Plantation. The Dr. Watson Inn, a bed and breakfast that is part of Flowers Plantation, sits on the original site of the manor house and has some of the original wood framework. Josiah Watson also owned smaller plantations below Smithfield, NC, on the Neuse River called the Islands that he bequeathed to his nephews Henry Bulls Watson, William H. Watson, and George W. Watson. Dr. Watson also owned land and plantations in Lawrence County, Alabama, and Courtland, AL, that were managed by his brother John Brown Watson.
Family
Josiah Watson married Penninah Tartt of Edgecombe County, NC, on 6 December 1818. She was the daughter of Elnathan Tartt and Obedience Thomas. Their only child was a daughter Elizabeth Obedience Watson who was born 24 September 1819 and died 3 December 1839 in Wilmington, NC, on the way to Cuba for treatment of respiratory distress. Penninah Tartt Watson died 30 January 1848 at their home Sharon near Raleigh.
In 1836, Josiah Watson purchased approximately of land just outside the city of Raleigh, NC, in Wake County from John Sugg. The mansion on the estate had been built about 1805 by Heny Potter and named Sharon before he sold the estate in 1822. The estate covered an area from the original 1792 city limit southeast of Raleigh east to the rock quarry and south across Walnut Creek. After Josiah's death, the main house on East Lenoir Street was sold to State Treasurer Jonathan Worth before he became governor and is also known as the Watson-Worth House. It was later bought by Josiah's nephew J. W. B. Watson and after his death sold to the city of Raleigh to be transformed into the Crosby School for Negroes in 1897. The house was torn down about 1936, and the Crosby-Garfield School now occupies the site. Much of the land is still used for parks, public schools and community centers. One part of the estate was developed into a residential community in the early 20th century and named "Watson Addition."
In 1849, Josiah O. Watson was appointed by the North Carolina General Assembly to a commission of six men to select a site and oversee the construction of the Insane Asylum of North Carolina, later known as the Dorothea Dix Hospital. The other men were Governor John Motley Morehead, Senator Calvin Graves, Dr. Thomas N. Cameron, George W. Mordecai, and Major Charles L. Hinton. The Insane Asylum is located on Dix Hill in Raleigh, NC, and was opened in 1856.
In 1849, Dr. Watson was a strong proponent of the North Carolina Central Rail Road. He individually subscribed $10,000 of stock in the North Carolina Railroad and owned 40 shares of company stock at his death. Construction began in 1851 and was completed in 1856.
Dr. Watson was a parishioner at Christ Episcopal Church, and was baptized there on 12 January 1840. He represented the church as a lay delegate at many annual conventions of the Episcopal Church of North Carolina. In 1851, he purchased 5 pews to support the completion of the interior of the new church. In his will, he bequeathed $2500 to be used to finish the tower and steeple of the church, which was completed in 1861. He also gave the church $5000 to be used to fund and employ a teacher for a parish school. A small school was established in 1868, but, in 1937, the Ravenscroft School was organized using the original funds directed by Dr. Watson.
