"The Newtons are a large tribe, spread over England and America, of Anglo Norman origin. We find them in England soon after the advent of William the Conqueror, in Lincolnshire, Yorkshire, Glouchestershire, Herefordshire, and elsewhere in Scotland and Wales.   Newton, Nuten, Neuton, Newtten  . In New England as early as 1632, in Boston and along the Atlantic Coastline, in Maryland in 1660 where John Newton passed before going on into Virginia in 1670, in Westmoreland County only to discover Richard and Francis settled in a small colony in 1635 in James City County and Isle of Wright 1643. [RIVER OF YEARS, Joseph Fort Newton, J. B. Lippencutt Co., Phil., N.Y. 1946]. 
The Newtons took a leading part in Colony affairs. A number were Judges and influential in political life and civic life. Many were preachers, Episcopal, Presbyterian and Baptist. They pushed west into Georgia, Tennessee and beyond to the Texas Republic where they preached in small communities and established churches. Spiritually minded they sought a new life in new lands. 
It seems all Newtons from whatever origin must claim Sir Isaac Newton, 16421727, as their family. He never married though his half brothers did and he was born near Grantham in Lincolnshire. His great grandfather was related to the Newtons of Yorkshire. Sir Isaac inherited estates at Kingston in Yorkshire which was the family center for Virginia Newtons. Sir John Newton (of Barr's Court) said his line was Welsh and his great grandfather came from Trenewith at Poiseland or Powys, Wales. The translation of this to English means New Town. The family name was Caradoc and the ancestor was Sir Richard Caradoc, alias Newton, Justice in Banco. This name goes back to early British history to the Celtic Chiefton, Prince Caractacus who fought Caesar in 53 AD and later became King Caradoc. For sometime this branch came to Yorkshire and were called the Newtons of Barr's Court. Others came from Scotland and Northumberland. 
Others tell a story of three brothers who came to America from Scotland. Two returned to bring family and friends to the new world. The ship was lost at sea and the brothers were never heard from. These were grandsons of Robert Newton, younger brother of Sir Isaac Newton. One line stems from Ebenezer of York, Pennsylvania whose descendants often included the name of Benjamin, Calvin, John and Thomas. Some of these descendants came to Georgia and were Presbyterian preachers. One was Capt. Benjamin Newton, son of Ebenezer, born 1748, in York Penn. He served in the North Carolina Militia in battles against the "Tories". 
Another line was the Baptist Newtons who seem to have come from Putnam, Baldwin Co., South Carolina to Georgia shortly after the Revolution. Elder John Newton was a minister in Charleston, SC at the Charleston Baptist Church, according to Dr. B. Manly Sr., Historian. John was born 01 Sept. 1732 and died 26 Nov. 1790. The fact that he came from SC is the only history that I have for him. He was the father of the Revolutionary War hero Sgt. John Newton, b. 16 Jan. 1755 and d. June or July 1780, a prisoner on a British prison ship. Newton County GA. was named for him. John also had a son Moses and Philip Dorsett Newton. Elder John's diary, in the special collections of the University of Georgia Library. contains various items of his occupation in the Carolinas and N. E. Georgia. His son Moses, b 1765, d. 1824 was a doctor in the Savannah River Valley. John's diary was about work in Jefferson Co, near Fennis Bridge on the Ogeechee River. This John Newton preached at the Province Church in Jefferson County in 1787. In his diary he mentions JEREMIAH & JAMES MATTHEWS, SANDERS WALKER, PETER SMITH, and ABRAHAM MARSHALL. In 1790 he was at Kiokee Association Meeting of about 20 churches. John. Sanders Walker and several others were appointed as a Committee to set down rules of decorum. Sanders Walker was one of the earliest Baptist preachers, coming in 1772 to Georgia to the Kiokee church. [Mitchell, RIFE BALLS, HORSESHOES, WAGON WHEELS AND A BIBLE]
