Duncan Gray enlisted in the service of the United States, marched to the front, took part in the battle of Chippewa in the war of 1812, and was lost in that engagement; but in what manner he was killed is not known, as he has never been heard of since. His widow died July 14, 1847, aged eighty-one years. They had eight children, viz: Hugh, Daniel, James, Mary, Thomas, William and Jane, none of whom are now living except Thomas, who was born August 18, 1798, and lived at home with his mother until two years after his marriage, assisting his mother in the management of her small farm, and occasionally attending school winters. His advantages for obtaining even a common school education were extremely limited, as all of his time and best energies were required to secure a scanty living for his mother, two younger children and himself.

On the 21st of April, 1826, he was united in marriage with Mary, daughter of Benjamin and Isabell (Hunter) Wynn, the latter of whom was the widow of Jonathan Haynes, one of the first settlers in the town of Geneseo. She was born Feb. 10, 1805. Thomas Gray is one of that band of resolute spirits who helped to clear away the forests, lay out roads, build bridges, and erect school houses and churches. Beginning life a poor boy, with no advantages, and nothing but his native energy, perseverance, and unswerving integrity of purpose, he has attained a fair success in life. He settled on the farm on which he is still living in 1827, occupying a board shanty, until he finished a small house, having chopped away a place in the woods for that purpose. He then commenced clearing off the original forest from his land which, after many trims and privations, he accomplished. Now at the advanced age of eighty-three years, his step is firm and he is in the possession of his faculties to a remarkable degree. Much of his success in life is due to the assistance rendered him by his faithful wife who has ever been ready with good, kindly advice and wise counsel. She has toiled early and late in her husband's interests, and in assisting and teaching her children. Home has been her province, and love her scepter. Mr. Gray has never been a member of any church, but has attended the Presbyterian church at Lakeville, of which his wife has been a member forty-six years. He has been A member of the Republican party since its organization, giving a hearty support to its principles, but has never been an office seeker.

In all business transactions he has endeavored to be strictly just, and has passed through life without a stain resting upon his character. There have been born to Mr. and Mrs. Gray six children, as follows: -Catherine, born Sept. 21, 1826, died Dec. 21, 1866; Daniel Harvey, born Sept. 7, 1829, unmarried; Lydia Maria, born May 13, 1834, married to Lorenzo P. Roe, of Geneseo, and residing in that town: Josepha, born July 8, 1836, married to Wm. Davis, of Geneseo, and residing in the town of Avon; Leonora Elizabeth, born July 20, 1844, married to Thomas Jefferson Wynn, of Geneseo, and Edgar Lotharin, born Feb. 20, 1849, married to Martha Diefenbacher, of Geneseo, by whom he has one son, Clyde D., born Dec. 30, 1876.

Lydia united with the Presbyterian church, of Lakeville, in the spring of 1853, Josepha at the same time and Leonora in the spring of 1865.(Smith, Livingston County History, 1881. p.f.383)
