There was a John LOW of Clermont Co., OH, by 1810.

RootsWeb says one John LOWE was possibly father of Elijah LOWE (9 Aug. 1796, MD - 21 Dec. 1860, bu. Village Cem., W. Union, Adams Co., OH) who m. 14 Je. 1819, Worc. Co., MD, Hester Ann "Hetty" SMITH (13 Dec. 1801, MD - 21 Oct. 1883, OH). Will of Elijah named wf. Eliz. and brother Kendall.

In Tiffin, Adams Co., OH, 1880, Hester LOWE, 78, MD MD MD, was with widowed dau. Emeline BURBAGE, 61, MD MD MD.

One Kendall LOWE m. 31 Oct. 1820, Worc. Co., MD, Eliz. WHITE.

Hudson LOWE (17__ - 1849) Sabina HUNT had bond of marriage 17 Apr. 1818, Mason Co., KY. Hudson & Sabina had son Thomas (ca. 1821/5 - 15 Feb. 1897?) Adams Co., OH. In 1870, Sprigg Twp., Adams Co., Sabina, 76, was with son John H.

In 1880, Bradyville, Adams Co., Sabina, 90, VA IRL IRL, was with son Thomas, 55, OH MD VA. She aged 14 years in 10. :-)

In Clermont Co., OH, 1820, 1830, & 1840, there was a Barton LOWE who might have been related. His pension file said he was b. 2 May 1762, Prince George's Co., MD. He served twice in the Revolution, 1781 & 1782, & m. 10 Feb. 1782, Upper Marlboro, PG Co., Susanna HOLLINGSFORD. He moved to Loudoun Co., VA, ca. 1795, and lived there 11 years before moving to Ohio. There were children, but they might have been by another wife because of the birth dates. In 1860, Clermont Co., there was an Eleanor, aged 78. Barton LOWE probably had

Samuel B. LOWE
Barton LOWE (4 Nov. 1808 - 31 Jan. 1884, Winchester, Adams, OH)
Gideon M. LOWE (1811 - 19 Nov. 1894/5? bu. Mt. Zion) m. 19 Mar. 1835, OH, Mary THOMAS. In 1880, Pike T., Brown Co., Gideon M., 69, & Mary, 61, had six of their children, still single, with them. See FamilySearch (free) database.

I thought Alex B. might have been son of Barton, but in 1860, Fayette Co., PA, there was a Michal, aged 71, as well as Alexander, 46; Maria, 44; Sarah, 22; Mary, 18; Wm., 16; Joseph, 12; Thos. & Maria, 10; Alonzo, 8; Samuel, 3; & Virginia, 10 mos. That must have been Alexander B. (1 Jan. 1813, OH - 17 Apr. 1892) who m. Maria Catherine REPPERT (25 Mar. 1815 - 4 Sep. 1888). In 1880, Alex B. LOWE, 67, OH, lamp lighter, & wf. Maria, 65, PA, were of Ottawa, LaSalle, IL, with dau. Virginia, 19, PA.
