I went in pursuit of an answer as to why Ruth Sieurin was listed as a World War I veteran in the records of the First Congregational Church in Shrewsbury, Massachusetts. Simple answer is that she was a nurse. I found an informative listing on the Arlington National Cemetery Website, under an entry for her husband, Willard Stewart Paul, a US Army Lieutenant General (http://www.arlingtoncemetery.net/wspaul.htm : 21 November 2009).
The webmaster Michael Robert Patterson does not cite any sources (except for the gravestone photos), but he seems to have given careful consideration to ascertaining his facts. Willard S. Paul married Ruth M. Sieurin 14 April 1919. Ruth passed away 4 February 1953, and Willard married 2nd Luella Musselman. Willard passed away 21 March 1966. Luella passed away in 1978. Though she is not shown on the gravestone, Patterson says that Luella is also buried there.
