This Chamberlin is not in my direct line but I include him here because of the detailed biography.
From the Genealogical & Biographical Annals of Northumberland County, 1911.
HARRY W. CHAMBERLIN, of Milton, Northumberland county, president of the Milton National Bank, lawyer and present borough solicitor, is a member of the third generation of his family to reside in that place and most worthily bears a name which in every generation within memory has had notable representatives. In both his professional association and his relation to the bank he is practically the successor of his grandfather, W. C. Lawson, with whom he studied law and who was president of the Milton National Bank for many years from its organization. Thus, though he had many advantages of position and education, instead of the usual difficulties which confront the young man who cares to make a name for himself, he had to take up the burden of maintaining a standard already set. That he has proved himself able to do that and more his standing in professional and financial circles in Milton today, which is second to none, clearly shows.
Mr. Chamberlin was born Aug. 29, 1872, in Milton; son of William B. Chamberlin. His grandfather, Moses Chamberlin, was born in Union county, Pa., and his great-grandfather, William Chamberlin, was a native of New Jersey, born Sept. 25, 1736, in Hunterdon county. He was a lieutenant colonel in the New Jersey militia, and served as such in the Revolutionary war. Having a soldier’s warrant, about 1792 he removed to Buffalo valley and purchased six hundred acres of land at what is Hoffa’s Mill, in what is now Kelly township, Union county, where he lived in prosperity until his death. The original mill there was erected by his son William. He was a prominent member of the Baptist Church, and died Aug. 21, 1817.
William Chamberlin was four times married. On June 8, 1758, he married Elizabeth Tinbrook, who was born Aug. 23, 1740, and died April 29, 1770. This union was blessed with the following children: Lewis, born April 16, 1759, who was killed by a cannon-ball at the battle of Germantown, while on a visit to his father (his knee was shot away, and in that day of primitive surgery the injury necessarily proved fatal); Nellie, born Sept. 13, 1761, who died July 3, 1817; Ann, born April 18, 1763; a daughter, born Nov. 12, 1764, who died Dec 19, 1764; Lucretia, born Dec. 20, 1765, who died Jan. 19, 1841; John, born April 10, 1768, who died May 5, 1770; and William, born April 20, 1770, who died May 5, 1770. On March 3, 1771, Colonel Chamberlin married (second) Ann Park, who was born in 1762 and died April 29, 1791, the mother of four children: Uria, born June 21, 1783, who died Feb. 4, 1853; Elizabeth, born May 22, 1785 (Elizabeth McCrary died March 22, 1827); Aaron, born May 24, 1787, who died Jan. 12,1856; and Rachel, born Sept. 16, 1789, who died April 9, 1791. The Colonel’s fourth marriage on Aug 16, 1794, was to Ann Mary Kemble, who was born Nov, 28, 1769, and died March 4, 1859. She came of an old family, of considerable standing, and was on terms of friendship with George Washington, Washington Irving and other people of note. She was a member of the Presbyterian Church and a devout student of the Bible, many chapters of which she committed to memory. She was the mother of eight children, namely: Lawrence, born Aug. 4, 1795, who died in 1802; John, born Feb. 8, 1797, who died April 18, 1858; James, born Sept. 30, 1798, who died Aug. 30, 1801; Lewis K., born April 4, 1803, who died Aug. 10, 1889; Mary F., born Sept. 29, 1804, who died April 3, 1865; Joseph P., born Sept. 18, 1806, who died Feb. 13, 1873; James D., born Oct. 29, 1809, who died Oct. 11,1886; and Moses, born Nov. 12, 1812. William Chamberlin, eldest son of William by his second wife, married Nellie Sutphen, who was born Nov. 11, 1771, and they had children born as follows: Anna, July 15, 1793; Mary, March 19, 1795; John, Sept. 1, 1796; Nelly, March 23, 1798; John, Dec. 31, 1799; Sarah, Feb. 12, 1802; Lillen, Jan. 22, 1804; William, May 3, 1808; Lucretia, June 15, 1810; Aaron, Sept. 12, 1812.
Moses Chamberlin, son of Colonel Chamberlin, was born Nov. 12, 1812, in Union county, Pa., the youngest of his father’s twenty-three children. He was reared on the paternal homestead and received his education in the typical schools of the period. When twenty years old he went to Lewisburg where he served a three years’ apprenticeship at the tanner’s trade, which, however, was never his principal business. In 1833 he removed to Milton, where he had a long and prosperous business career. He was a merchant, and also enraged in milling, lumbering and farming, continuing his active life until 1874, after which he lived retired. Besides conducting these various enterprises he purchased land and laid out what is known as the Chamberlin addition to Milton, and also laid out and sold the land upon which Watsontown is situated. His long and useful life ended July 29, 1902. Though busy with his personal affairs he found time to serve in several borough offices and also to be an active member of the Methodist Episcopal Church, which he served in many official capacities, being trustee, recording steward, class-leader, Sunday school superintendent, etc. He was a Republican in political sentiment.
In 1835 Moses Chamberlin married (first) Mary Ann Corry, daughter of George Corry, of Milton, and to this union were born two children, Elizabeth H. (widow of William Follmer, of Watsontown) and Mary A. Mrs. Chamberlin died Aug. 15, 1838, and in 1840 Mr. Chamberlin married (second) Mrs. Jane Hannah (Watson) Montgomery, daughter of John Watson, of Watsontown. Six children were born to this marriage, viz.: William B.; Harriet, deceased; Caroline W., Mrs. A. O. Furst, of Bellefonte; Mary Jane, deceased; James, of Harrisburg; and Frank, an attorney of Milton. William B. Chamberlin, son of Moses, was born Dec. 19, 1841, at Milton, Pa. For years he has been one of the notably successful business men of the upper end of the county, having been from 1867 to 1885 engaged in the lumber business at Northumberland as junior member of the firm of Chamberlin, Frick & Co. In 1885 he became connected with the Reid Tobacco Company, of Milton, of which corporation he is vice-president and he makes his home in the borough, where the business with which he is identified ranks among the most important concerns. He married Margaret Sanderson Lawson, daughter of W. C. and Hannah (Sanderson) Lawson, and they have had three children, all sons, namely William L., a mining engineer, now located at Scranton, Pa.; Harry W.; and James S., who is connected with the American Car & Foundry Company of Manchester, England.
Harry W. Chamberlin attended the public schools of Milton, graduating in 1887, after which he became a student at Lafayette College, from which institution he was graduated in 1892. He read law with his maternal grandfather and was admitted to the Bar of Northumberland county in 1895, since which time he has been continuously engaged in legal practice, occupying the same office which his grandfather had. His patronage has been steady and lucrative from the beginning, and the able manner in which he handles legal work has drawn a high class of such business to him. His inherited and developed talent for the profession, and his accomplishments in special cases, entitle him to a place among the most skillful lawyers of his day in his section. On Oct. 29, 1903, Mr. Chamberlin married Miriam A. Bucher, daughter of, ex-Judge Joseph C. Bucher, of Lewisburg, Union Co., Pa., and his wife, Mary (Walls), daughter of Judge Walls. Mr. Chamberlin’s grandfather was Rev. Joseph C. Bucher, D. D., a well known clergyman of the Reformed Church. Mr. Chamberlin is a high Mason, holding membership in Milton Lodge, No. 256, F. & A.M.; Warrior Run Chapter, No. 246, R.A.M., of Watsontown, Pa.; Mt. Hermon Commandery, No. 85, K.T., of Sunbury; Williamsport Consistory, A.A.S.R., and Irem Temple, A.A.O.N.M.S., of Wilkes-Barre. He is also a member of the Zeta Psi fraternity, and an active member of the Presbyterian church. In political preference he is a Republican.
