GAD LAMB.-The third settler was Gad Lamb, from the town of Wilbraham, ten miles from Springfield, Mass., where he was born November 20th 1744. He was married January 7th 1779 to Jerusha Ripley, of Windham, Conn., daughter of Ebenezer and Mehitable Ripley. Their children were Daniel, Harry, Sally, Patty, Jerusha, Lorain, Nancy, Clarissa, Maria, and Ebenezer Ripley, of whom all but Lorain are dead. Mr. Lamb died at Lamb's Creek, April 5th 1824, aged 80 years; and wife May 9th 1838, aged 82. They are buried by the road side half a mile below Lamb's Creek, and a few rods north from the spot where they lived.
Fortunately, of this old and well known family there remains a living representative in the person of Lorain Lamb, besides numerous descendants. Unlike the settlers already named, who were transient, this family came to stay, remaining as prominent actors in the history of the township. Undoubtedly to Gad Lamb must be given the credit of being the first permanent settler, and it gives us pleasure to record him as such, with the suggestion that when, it a few years, we shall celebrate the first centennial in the history of the settlement of our town, a stone be placed over this grave perpetuating his title to this honorable distinction.
Mr. Lamb was a man five feet ten inches in height, and weighing 240 pounds. He was broad-shouldered and very strong. He had heavy eyebrows, dark hair and dark complexion. On the way here he made a stop at Towanda, where his son Ebenezer Ripley Lamb was born, May 21st 1797. Leaving his family there, he, in company with his oldest son, Daniel, came on to the Tioga River at Canoe Camp, where they looked at some land with the view of purchasing. They did not purchase however, but planted the old Williamson encampment to corn and potatoes. This was but a mere nook in the forest, cleared off by Williamson's men for a camp. They then went on down the river four or five miles and purchased the Carter place of a Mr. White, as already stated. Mr. Lamb then went back after his family, leaving Daniel alone in one of the log houses built by Carter, where he stayed for a period of two weeks, or until his father's return, listening at night to the howling of wolves, , with no human beings nearer than the family of Nathan Niles, at the mouth of Mill Creek.
Quite a feat for a boy of barely seventeen summers. On his return, Mr. Lamb's daughter by his first wife, a Mrs. Bartlett, was delivered of a boy when about four miles above "Peter's Camp," now Blossburg. This child of the wilderness was name Judah. Mr. Lamb with his family reached their destination on the evening of July 4th 1797. They resided for about three years thereafter in one of the log houses built by Mr. Carter. They then erected a large double log house on nearly the same ground, which stood on the spot where John Lanigan's house now stands, nearly half a mile below the Lamb's Creek bridge. South from this house Gad and his sons, Daniel, Harry, and Lorain, planted the first apple orchard ever planted by white men within the limits of Richmond. When Gad and his sons went to mill they put their grain in a canoe and went down the river to Elmira, then Newtown, a distance of fifty miles or more, and on their return poled the canoe back. When they could not do this they had a large stump hollowed out, and a spring pole pounded out their own grain. Gad's wife, Jerusha, organized the first Sunday-school in Richmond, at her own house, fifty-six years ago.
