In 1775, at the age of 18, Noah Tyson like many of his other relatives joined the Pitt County Committee of Safety during the time of the American Revolution. The Pitt County Committee..., like others across the State, raised militia, provided for arms and the relief of the poor. They tried people for offenses, routed out Tories and appointed patrollers to regulate slaves. They also took interest in and controlled the educational and religious aspects of the county.

Noah Tyson appears to have had a strong religious upbringing and was to become a noted local Baptist minister. In 1796, he was minister to the Great Swamp Church in Pitt County, which was received into membership in the Kehukee Baptist Association.

In Hassel’s history of the Church of God, he mentions that the Great Swamp Church, 4 miles north of Greenville, was a branch of the Flat Swamp Church, which was dismissed in 1795 and took the name Great Swamp. Rev. Noah Tyson, a member of the church at Red Banks, was called to minister. He was described as 'a man under bodily affliction and yet he did not neglect his families.'

The Bible used by Rev. Noah Tyson was once in the household of his great grandson, Dr. B. T. Cox, in which could be found a record of the funeral sermons Rev. Tyson preached in nine years. ... The aggregate is 757 which seem to be a very high number, but it is probably due to the lack of preachers in the area than the frequency of deaths.

Noah Tyson was also a large landowner and operated a water saw and gristmill on Hardees Run. Robert Forbes who married one of Noah Tyson's daughters eventually bought the mill from the heirs of Noah Tyson and it stood until 1927 when it was known as Forbes Mill Pond. Some of Noah's land grants include 250 acres to his son James, that is now the site of the Greenville Golf and Country Club. The mill was situated on the Greenville Country Club, near the old Tyson/Forbes Cemetery.

Moses Tyson Jr. died May 15, 1803 without making a Will. On November 9, 1803 his heirs, 'all being of full age to act for themselves' authorized Noah Tyson (their brother) to administer the estate and make sales of the property so that each heir may receive an equal division of the estate. The authorization was signed by each of the children of Moses Tyson viz: Tamar Tyson (md. Jonathan Mears); Enoch Tyson; Rachel Tyson (md. Zachariah A. Allen); Noami Tyson (md. James Mears); Esther Tyson (md. ___ Nelson); Mary Tyson (md. William Beddard); Timma Tyson (md. Joshua Patrick); and Moses Tyson.

Tamar Tyson was married about 1798 to Jonathan Mears and lived in Bladen County, NC. Naomi Tyson also married about 1798 to James Mears and lived in Bladen County. On May 3, 1819 Naomi Mears sold 100 acres in Bladen County to her son, Bethel Mears. Bethel Mears later married Margaret Ann and had the following known children: Obeda Lini Mears, Bethel Mark Mears and Daniel
