I have wondered why early mentions of the surname Covalt are scarce.
The "History of Sussex and Warren Counties, New Jersey, with Illustrations and Biographical Sketches of its Prominent Men and Pioneers" compiled by James P. Snell in 1881, shows on p. 32 that after 1735, among the earliest settlements east of the Blue Mountains "was in the Popakating valley and was made by Messrs. Colt, Price, and Gustin, who were originally from New England. ...they removed to Orange co., N.Y..." The book doesn't give the date for the time Messrs. Colt, Price, and Gustin arrived in NJ. Interestingly, "The Gustin Compendium" shows many CT land transfers between and among John Gustin, Sr., John Gustin, Jr., and various members of the Colt family. It seems highly probable that there is some relationship between the Gustin & Colt families and their appearance in CT and NJ together.
Colt - Coult - Covalt - - -
Abraham Colt/Coult Abraham Covalt.
I wonder if we've been trying to force the spelling to find Covalt.
The closest record I've see to identity of Elizabeth Gustin as the wife of Abraham Covalt is in a letter written by Jonathan C. Dove (b. 1807) to his son Garrett in 1884. In the letter Jonathan identifies the surname of his grandfather's and greatgrandfather's wives, "Grandfather's name was Abraham Covalt, or Coalt as it was spoken then. His father's name was also Abraham and his grandfather's also. His father was American born but his grandfather was a Holland Dutchman. He must have been in the first settlers in the eastern colonies. My grandfather Covalt was old enough to serve in the French and Indian wars, before the revolution. This I think happened before he left Massachusetts. He served on the ocean or was at least in the Indian islands at the taking of Martinco. His mothers name was Gustin, and she was of French descent but I think American born. I have seen people of that name that I thought resembled the Covalt, family."
A repeat from above, "Grandfather's name was Abraham Covalt, or Coalt as it was spoken then..."
Covalt. Coalt. Colt. Hmmm...
Maybe my genealogical blinders have been on my head.
I have ancestors' names that have changed from Berg to Barrick. Another from Brand to Brandt. Hmmm...
re: Fuller. I don't have the information on the Fuller descendants beyond the first five generations shown in the Mayflower Society "Silver" book on the descendants of Edward Fuller. It was my source of Elkanah Fuller as the father of Bethany Fuller, who married Jeremiah Gustin, youngest sibling of Elizabeth Gustin, d/o John & Mary Gustin. Elkanah Fuller was the minister in Sussex Co, NJ for the 1763 weddings of Abraham Covalt & Lois Pendleton as well as Jeremiah Gustin and his daughter Bethany Fuller.
Interestingly, Jeremiah Gustin was born in Glastonbury, CT, a home of the Colt family. From above we know Gustin and Colt were early Sussex Co, NJ pioneers.
Elkanah moved from E. Haddam, CT to Mansfield, CT to Sussex Co, NJ before 1763 to NY.
I think I'll take a chance and look for marriages in CT between an Abraham Colt and Elizabeth Gustin.
The LDS Ancestral File lists the birth of an Abraham Colt on 30 Sep 1714 Glastonbury, CT, s/o Abraham Colt. [Jonathan Dove said his Covalt/Coalt ancestors were Abraham -> Abraham & Gustin -> Abraham.] Abraham Covalt was born in Great Egg Harbor, NJ 9 Oct 1714 according to some Buck researchers and 1714 according to C. Richard Covault's book.
