"GEORGE W. CHAMBERLAIN was born in Carroll County, Indiana, September 12, 1836, and is one of ten children born to AARON and ELIZABETH (THATCHER) CHAMBERLAIN, viz., JOSEPH, HENRY, HENRIETTA, DANIEL, GEORGE, EMELINE, CAROLINE, MARY, JOHN, and AARON, of whom HENRIETTA, EMELINE, CAROLINE, MARY, and AARON are deceased. The father of GEORGE was born in New Jersey in 1802, was a farmer by occupation, and died in this township in 1849. When very young, GEORGE came with his parents to Tippecanoe County, Indiana, located at Battle Ground, and in 1844 removed to West Point Township, White County, they being the fifth family to enter this location. On March 15, 1860, GEORGE W. CHAMBERLAIN was married to ELIZA ROBINSON, by whom he had nine children - EVA, MARY, CAROLINE, ROSA, JOHN, JOSEPHINE, LEE, ROBERT and SARAH, of whom the first three are deceased. MR. CHAMBERLAIN's residence is eight miles southwest of Reynolds, on a 520 acre farm; he has also 213 acres in timber, three miles north, and 160 in Kansas. He raises chiefly hay, corn, and oats, but makes a specialty of raising cattle. MR. CHAMBERLAIN is one of the earliest settlers, as he is likewise one of its most respected citizens."
