In this past week I have discovered a great aunt, Eva Aubut/Obert, who married Peter David Kyer, son of Thomas Kyer and Adelaide Rodderick, 23 Feb 1914 in Gorham, NH. By 1920 Peter has passed away and left Eva with 2 toddlers: Frances (born 1917) and Grace (born 1919). Peter and Eva also had 2 little girls (Mary and an unnamed child) that passed away as infants. As far as I can tell, Frances is the only child of this union to survive, as Grace passes at age 13.
What I am looking for is a death date for Peter and what may have happened to Frances. All help is appreciated.
