Either Sarah was mistaken about her birthplace, or the family moved back and forth between Canada and Michigan.

"Catharine"?  Shouldn't she be Mary Cynthia?  Or is Hopkins (1932: 344 — see below) wrong about her middle name?

NORMAN7 (NEHEMIAH,6 NEHEMIAH,5 EBENEZER,4 EBENEZER,3 STEPHEN,2 JOHN1), b. at Pittsford, Vermont, 17 July 1790; m. at Chatham, Ontario, Canada, 21 January 1815, Mary Cynthia Loucks, b. at Schenectady, New York, 20 Jun 1792, daughter of Henry Alvah, b. Jun 1764, and Katherine (Shuke) Loucks.  He d. at New Brunswick, Michigan, 8 January 1852; she d. at Caro, Michigan, 1 July 1881. In about 1802 he removed from Vermont to the Genesee River, New York, where Rochester now stands.  He served in the War of 1812 as a private in a New York regiment, received a bayonet through his leg at the battle of Lundy's Lane, and was discharged at Detroit, Michigan, in November 1813, where he remained.  In 1832 he was a Captain of Infantry in the Blackhawk War.  His name appears among the charter members of the First Presbyterian Church of Detroit.  At the time of his death he was in the real estate business. Children:      LUCY ANN,8 b. 14 October 1816.      CHARITY MELINDA8 b. 23 December 1818, at Detroit...      WILLIAM ALVAH,8 b. 16 January 1821; d. at New Baltimore, Michigan, 1852; unm. 410. HENRY LOUCKS,8 b. 16 February 1823; m. Mary Almeda Mills.

In the censuses, Norman's wife is either, "Mary," "Mary C.," or "Catherine."  So, is her middle name really "Cynthia"?  There's no such place as New Brunswick, MI, but there is a New Baltimore in Macomb Co., MI, in which county Norman was living in the 1850 census, just two years before his death.  Note that Norman's son, William Alvah, is said to have died in New Baltimore.  Birthplaces are not given for any of the children, except Charity Melinda, and that one appears wrong based on her birthplace as given in the censuses.  In the censuses, Sarah was always either just, "Sarah," or "Sarah A.," never Miranda or Sarah M.  See children's family group sheets for more of their entries.
