Since the name was George Barber.... Frederick seems to be the son of Barber Clute and Amelia. They had George born 19 Oct 1875 and Frederick 6 January 1879. They lived in Fulton, Johnstown. They were in both 1880 and 1900 census. In the 1880 a niece Alice White 18 was also with them.
Barber is the son of John S. Clute and Aretta. Barber was born 7 August 1853. If you would like more information on the line, please email me.
The name Barber is unique in the Clute family to this one man, so I truly think this is the right family.
