Who did Joseph Dubois marry? Did he marry Marie Alma Harper.
I have their marriage as 11 Jan 1909 in Fisherville (Grafton), MA.
His was 23 at the time of the marriage, born in Sutton, MA. His parents are Nelson Dubois and Adella Brough.
A birth of (male) Wood in Sutton, MA on 06 Sep 1885, parents are Nelson Wood (b. 1857) and Adella Broche (b. 1854). He was born in Lowell, MA and she was born in Black Booth, NY.
Joseph had a brother Nelson Wood who was born in Suncook, NH in 1878, he married Rosa Nero in Grafton, MA in 1900.
He also had a brother Ernest born in NH in 1879.
You may have the wrong Nelson Dubois to Adella Brough marriage in 1890. I say they were probably married in New Hampshire about 1876-1877.
I found this family in the 1880 Census in Pembroke, NH.
