Married Alche Wyckoff
Jacob, son of Tunis, was one of many who went with Washington in 1780 to the Mohawk Valley in New York State to subdue the Indian depredations. Finding the valley so rich and beautiful he purchased a farm containing buildings and improvements from John Watts, the father-in-law of Sir John Johnson. He remained a year and sowed a crop of wheat and reaped it, which he sold for a dollar a bushel, and thus paid off his indebtedness of $1100. He then returned to his family in New Jersey, who came with him to their new home. Their son Garret came with them. There was a general exodus from New Jersey westward. Albert Couvenhoven and his wife Patience located near Garret's new home. They had occupied in New Jersey the adjoining farm to his Grandfather Tunis Vanderveer. They brought with them their daughter Rachel. She as a child of ten years, helped to carry water on that terrible day in June, 1778 from the spring on her father's farm. There were living in 1910 those who had heard from her lips the story of that day. The night before the battle her father's house was used as a shelter for the women and children of the neighborhood. She told with pride of the good night visit made by Washington accompanied by Lafayette. The former shook hands with them, followed by a kiss from Lafayette, and then the two sought their nights rest under a nearby tree. The day of the battle, she witnessed the meeting between General Washington and General Lee and says: "What General Washington said to General Lee was not expressed in very nice language." Time passed and in 1788 she married Garret Vanderveer. From them was descended the eminent physician and surgeon Dr. Albert Vanderveer of Albany, NY.
