Photograph of Rev. William Shepherd Dunn, Wife Annie Louise (Vinal) Dunn & a Vermont Congregration

Photograph of Rev. William Shepherd Dunn, "Will", and wife Annie Louise (Vinal) Dunn, along with their congregation at a church in Vermont, possibly at Waterbury Center or Isle La Motte.

The photograph itself is a little shy of 7" by 4-1/2".  Mounted, the piece is 10" by 8".  The reverse bears handwriting in ink which may have been added at some length after the photograph was taken.

From brief online research, hopefully correct - corrections and additions requested:

Rev. William Shepherd Dunn, "Will", was born February 25, 1868 at Poland, Maine, the son of Charles Wesley Dunn and Sarah Amelia (Pendexter) Dunn.

Will attended Bates College, and, presumably, Cobb Divinity School, at Lewiston, Maine.  He then served, according to the following excerpt from a 1915 Bates publication, General Catalogue of Bates College and Cobb Divinity School, 1863-1915:

• principal of the high school at St. Albans, Maine from 1888 to 1889
• at the Normal Academy at Booneville, Kentucky from 1889 to 1890 
• at the high school at North Berwick, Maine from 1890 at least until the date of the publication

On June 2, 1898 at Westborough, Massachusetts, Rev. Dunn married Annie Louise Vinal, daughter of Joseph Parker Vinal and Sarah Elizabeth (Richardson) Vinal.  At the time of their marriage, Rev. Will was a clergyman at Waterbury Center, Vermont; Annie gave birthplace and then current residence as Westborough, Massachusetts.

Rev. Dunn and Annie had 8 children by the time Annie died in 1914, presumably in childbirth with her ninth child, who died at birth.  Rev. Dunn's Find a Grave memorial notes that Rev. Dunn had a hard time raising the children - some went back and forth from his care to Vinal and Dunn family members; the youngest, named for his father, was adopted by the Lingley family. 

The birthplaces of their children include:

• Maine - Poland
• Massachusetts - Acton, Chatham, Nantucket, Westborough and Worcester
• Vermont - Isle La Motte

Throughout his life, Rev. Dunn was a clergyman, educator and farmer.  He died in 1954 and is buried in the Mount Auburn Cemetery at Auburn, Maine, with wife Annie and at least three of their children and Rev. Dunn's parents and other family members.
