Here is what I have: George Washington Haviland, b. 14 Jan 1843 in Norfolk Co., Ontario, d. 14 Sep 1921 in Saginaw, MI. Has a military gravestone (Company A 1st Mich. Infantry). Death certificate states he was a farmer, though he was a Justice of the Peace in Tittabawassi Township, Saginaw, MI. Death record states his father was Joseph and mother unknown, but I have his father as Benjamin Haviland, b. 23 Mar 1791, d. 20 Feb 1881 in Waterford, Ontario, and his mother as Lucy Craw, b. 12 Oct 1801, d. 22 Jan 1844 in Ontario. Benjamin & Lucy are buried at the Greenwood Cemetery, Waterford, Norfolk Co., Ontario. Benjamin was the son of John Haviland & Sarah Birdsall. John was the progenitor of most of the Ontario Havilands, having been born 21 Oct 1751 in Haviland Hollow, NY (which is about a 2 hour drive from where I live), near Putnam Lake. John's parents were Isaac "Tuck" Haviland and Elizabeth Bates; Isaac's parents were Benjamin Haviland & Charity Farrington (my 7th great grandparents); Benjamin's parents were Benjamin Haviland & Abigail Mott; Benjamin Sr.'s parents were William Haviland & Hannah Hicks. William was the immigrant to America from England, the progenitor of most of the North American Havilands. He was presumed to have been born 7 Sep 1606 in Salisbury, England, and died around 1697 in Great Neck, Long Island, NY. He was listed as a Freeman in Rhode Island on 17 May 1653 in the same document as Benedict Arnold, and became commissioner of that place 21 May 1656.
Back to George:
According to the Adjutant Generals Report: George resided in Kent Co.? and was discharged for disability on Nov 17, 1862. 1865-6 p. 54 (MI Vol. Records). George enlisted at Ann Arbor Jul 6, 1861 for 3 years at age 18. Mustered Jul 13, 1861. Discharged Washington DC Nov 17 1862 for wounds received in action Aug 30, 1862. Signed George Bennetts Naturalization Papers and stated his profession was Justice of the Peace. Married 26 May 1863 in Washington DC to Louisa Belle Turner, b. 15 Feb 1847, Washington DC, d. 12 Oct 1918, Saginaw, MI. She may have been a nurse at the hospital where George was recovering there.
Their children: George Benjamin, Richard Eugine, Victoria Elizabeth (Torrie), Andre Jackson, William Francis (Frank), Ellar Loretta (Nell / Nellie), Lucy Mae, Byron Loren (Barney), Mable (Maud), and Luise Belle (Lulla).
