Not my family line, just sharing.
**Note** The following is a Biographical Sketch of Henry Chamberlin, a brother to George W. Chamberlain. What is interesting yet frustrating is their surnames are spelled differently in the book, including the mother. It raises so many questions as to why?It just makes this research of families so challenging.

"HENRY CHAMBERLIN was born in Ontario County, New York, December 29, 1830, and is the second of ten children born to AARON and ELIZABETH (THACHER) CHAMBERLIN, natives of Pennsylvania and New Jersey. In early life, AARON CHAMBERLIN was employed in rafting on the Delaware River, and later in farming in Ontario County, New York, where he was married. In the fall of 1834, he bought his family to Carroll County, this State (Indiana); in the spring of 1837, he moved to Tippecanoe County (Indiana), where he farmed on shares until the spring of 1843, when he came to West Point Township, this county (White County, Indiana), and entered 160 acres of land, on which he resided until his death, February 9, 1849, followed by his widow May 30, 1882. HENRY CHAMBERLIN remained on the home farm until about a year after his father's death, when he went out to work by the month at farming and on the Wabash and Erie Canal, continuing about four years. In the spring of 1859, he bought his present farm of 160 acres in this township. March 2, 1854, he married CATHERINE J. BIDDLE, a native of Pittsburgh, Pennsylvania, and born March 11, 1838. To this union have been born five children, of whom three are living - CLARA J., HENRIETTA E., and EDWARD H. MR. CHAMBERLIN is a member of the Masonic fraternity, and in politics is a Democrat."
