This priceless photo was contributed by James H. Dickinson. In it we see four of Charles Decker's children, presumably in Warwick, Orange County, New York, around 1907.
Charles and Lydia were married about 1893 and together they had 7 known children:
Delaphine (later called "Mary") was born on 19 Jan 1897 in Port Jervis, New York.
Iona was born in Nov 1898 and died in Oct 1904.
Harry was born abt. 1901.
Norman was born abt. 1903.
Oscar was born abt. 1905.
Theodore was born in 1908.
Herbert was born in Feb 1910.
Based on this information, we can see the names on the photo are not in the correct order. The oldest boy, at left, was Harry. The youngest boy standing next to him would be Oscar, who was born abt. 1905. Mary stands third in line, and at right is Norman.
Assuming Oscar is approximately 2 years old in the photo, it was taken abt. 1907, three years after their sister, Iona, died. The following year, in 1908 their brother Theodore was born and on May 20, 1909 their father died from pneumonia. Lydia was pregnant with his final child, a son she named Herbert, born in February of 1910.
