I pieced together a story but have some gaps that I'm hoping someone can fill in! I'll post my questions in a "reply" post, as this got rather long!
Jonas born 1847 in Kansas (pretty sure the son of Daniel & Sarah Jane Loudon)
Agnes(s) born 1848 in Ireland (daughter of William and Ann Robinson)
Jonas and Agnes(s) marry
Children: • Daughter Eva born in 1875 • Son John L born in 1877 (later ran away from home... found a census for a J.L. Thatcher among a list of laborers, and an army enlistment record for John L. Thatcher with same birth year and birth place...no way to prove it is him, though.) • Daughter Jenna (Jennie) b Dec 1879 • Daughter Mary b 1883 • Son Harry b 1885 (found a Harry E Thatcher b. 1885 and d. 1917) • Homer Albert b in 1887
(((Agnes dies 1892)))
Jonas marries Laura E Fuller in KS in 1894 (she was b. May 1867 in Wisconsin to Edmond (from Mass) and Frances (from Maine) Fuller)
1895 Census: Kids in the home: Jennie, 15; Mary, 12; Harry, 10; Homer
Children born to Jonas and Laura: • Daughter Francis b. 1895 in KS • Son Clarence H. b. 18 Nov, 1896 in KS (d 23 Mar 1977 in Snohomish, WA) • Daughter Bertha Augusta Thatcher born 28 Feb1898 in KS, (later d. 12 May 1985 in Ventura County, CA) • Jonas N Thatcher (b. 27 Aug1899 in Kansas, d. 26 April 1969 in WA)
(((Jonas M Thatcher dies (1900 just before census))))
1900 census... wife Laura still living in Kansas, but older children not listed.
1903... Laura, Jennie, Clarence, Bertha, & Jonas immigrated to Canada.
1906... (They all showed up on census in Alberta... Laura owned 6 horses, 20 milk cows, 36 horned or meat cattle, and 4 hogs.)
1910 US census--Laura, Bertha, Clarence, and Jonah N. were living in Dayton, Waupaca, Wisconsin.
Also 1910 census...Homer was married to his 1st wife Estella & living in WA.
Bertha married Levi (Lee) Nutter from West Virginia. (b. 15 Dec 1892, d. 3 Dec 1961) on 13 April, 1918 *in 1920 census, they lived in Seattle, WA. Bertha's brother Clarence lived with them. *in 1930 census, they lived in Woodland, King County, WA... Children: Vivian (b. 13 Feb 1920 in WA, d. 28 Jan 2006 in Ventura, CA) & Lois (b. 1925)
Clarence married Elma (b. 6 Aug 1902 in WA. d. 10 Apr 1987) Her parents were born in Norway) No children listed in the 1930 census. (I'm actually assuming this is the right Clarence. He was born in Kansas and in 1930 was living in Darrington, Snohomish County, WA. The birthdates are right, and since he was living single in the previous census with his sister, I really think this is him.)
Jonas married Minnie M. (AKA M "Jennie") (b. 10 mar 1905 and d. 20 Jul 1989 in WA.) Same story as above, but these people were ALSO living in Darrington, Snohomish County, WA. So that I think solidifies my theory!)
