While in search of documentation for Civil War statistics, I discover the Fact Sheet: American Wars published in November 0f 2007 by the United States Department of Veterans Affairs. It provides the following:
It lists the last Union veteran as Albert Woolson (right) who died August 2 1956 at age 109. He was a member of Company C of the First Minnesota Heavy Artillery Regiment but never saw action. A brief biography is available here.
The last Confederate Veteran, John Salling, died March 16, 1958, at age 112. Some references, including one available here, suggests that he may have been an imposter.
And the last Union widow, Gertrude Janeway, died January 17, 2003, age 93. Mrs. Janeway death was covered in the January 21, 2003 issue of New York Times here. In brief, she was married to Union veteran John Janeway at age 16. He was 81. They made their home in a three room log cabin in Blaine, Tennessee. He died there at age 91 in 1937. She died in the same home. Mr. Janeway fought for the 11th Illinois Calvary under the name January. A photo of Mr. and Mrs. Janeway shortly after their wedding and of Mrs. Janeway in 1998 available here.
The last Confederate widow was Mrs. Alberta S. (Stewart) Martin who died in May 31, 2004. A site dedicated to Mrs. Martin including photos is available here. She was married to veteran Willaim Jasper Martin when she was 21 and he was 81.
A transcript of a 1998 interview with Mrs. Martin is available on radiodiaries.org here. Host Robert Siegel also interviews Daisy (Graham) Anderson who was, at the time, also one of the last know Union widows. Mrs. Anderson was married in 1922 at age 21 to Robert Anderson, then age 79, who was an escaped slave who joined the Union Army and served in the 125th Colored Infantry near the war’s end and in the Indian campaigns. He was a successful homesteader in Nebraska. Their story is available in the New York Times article about her death here. A article about Mr. Anderson’s fascinating life, titled “The Odyssey of an Ex-Slave: Robert Ball Anderson’s Pursuit of the American Dream,” by Darold D. Waxm is available through JSTOR here.
