Recollections of NewBern Fifty Years ago Alexander F Gaston married Eliza, a highly education , beautiful and accomplished young lady, daughter of Dr Hugh Jones. After marriage the lovers were settled on a rich plantation remote from city influences. The young wife became an admirable manager, sold the crops, laid in supplies, and by water-craft visited Newborn on business whenever necessary. After the death of his first wife, he removed to Burke county, in the mountains, where he formed a second marriage.

Death of Hugh Jones Gaston We record with much regret the death of Hugh Jones Gaston, Adjutant of the 48th NC Troops. He was wounded in the battle of Sharpsburg, in his shoulder and face, and died at a farm house near that place about the second week in October last. Adjutant Gaston was the youngest son of Alexander Gaston, Esq, who was the only son of the Hon William Gaston. His only brother, William Gaston, was killed by the Indians, near Fort Walla Walla, some four or five years since, in his first engagement and Hugh received his death wound in his first engagement at Sharpsburg. Hugh Jones Gaston was the last male of thence. Adjutant Gaston was physically except from military duty, but at the beginning of hostilities he volunteered as a private in an artillery company at Memphis and remained there until his native State was threatened, when he returned and offered his services to her. He was a young gentleman of fine education, modest, intelligent, and brave. His death adds another to the long catalogue of our bravest and best young men, who have been cut off by t his war. Raleigh Standard Alexander Gaston bears the name of his grandfather, Dr Alexander Gaston, victim of the Tories. He never approached his father in ability, and was more fold of field sports, in fact early in life all kind of sport, than business of any kind. His first wife was a daughter of Dr Hugh Jones,. Mrs Gaston was a lady of extraordinary business capacity …. and two sons. William was killed in his firs skirmish with the Indians , In Oregon just before the war. At the time he was in Col Stephens' command. Hugh Jones, his second son, had a short arm and was except from service. Yet he volunteered in the late war, and was Adjutant of the Forty eight N C .. He was possessed with the belief that he would be killed. in his first battle, and it turned out to be true. Being mortally wounded at Sharpsburg, his first fight, he died a week afterwards. Susan, Alexander Gaston's daughter, married Mr Bayliff and lived in Cuba. Her husband died, and she is now living in Boston. Some of our citizens can yet remember what a daring and graceful horsewoman she was when a young lady visiting Newborn some years ago.

Many Gaton families appear as minor characters in the story, although the main characters are entirely fictitious . It is not generally known that the famous old "Ingleside" built by the Forneys was the residence of Alexander F Gaston after the Forneys moved to Alabama. Alexander F Gaston was a son of Judge William Gaston of New Bern, for whom this city and county are named. Alexander Gaston was an educated gentleman who had attended the Catholic schools of his father's faith and wrote charming poetry. He lived at "Ingleside" only a few years, however, as his wife died shortly after he moved to this locality. Eliza Gaston is buried at Unity churchyard with a Latin epitaph on her tombstone.

Judge Gaston's son - he had but one, Alexander when at school was thought by some would in after life eclipse in intellect his father. The "Cat Hunt" written by Alexander Gaston , when he was quite young, for a Northern sporting magazine, was an admirable picture of the chase, and it was then believed he would gain an enviable reputation at least in literature.

The poem, first stanza here, was written in honor of our volunteers in the war with Mexico -
THE VOLUNTEERS ( by Alexander Gaston)
They are gathering, they are gathering
For the cabin and the hall,
The rifle leaves its bracket,
And the steed must quit its stall.
The country sends its thousands
And the city pours its throng,
To resent their Country's insult,
To avenge their Country's wrong…….
