Two of Ichabod and Anna's children survived to be counted in the 1880 USC. They both indicated that their parents were born in RI.That may be true for Anna (b c1775)but not for Ichabod or his father who were born at Stonington CT. Anna may have been a granddaughter of Sylvester (b1710) and Anna (Barber) Kenyon (b 8 Oct 1717). A son of theirs (Giles, b 1735 m Priscilla Briggs) lived at Hinesburg VT. Two sons of Giles, Azariah (B1769)and Giles, Jr., were at Hinesburg, VT. There is a 5 to 6 year gap (1771 to 1782) in the birth of Giles Kenyon's [Sr.](b1735)children in which a dau Anna could have been born but not recorded.
Interestingly, Ichabod and Anna (Kenyon)Niles' son Carlos (1815 VT-1898 KS) married Rebecca Kenyon (b 1812-d Sep 1879). She and Carlos lived in Kansas.
