I just happened to notice the probable reason that Laura Hungerford was mistakenly identified as having married a Cheney: her husband, Austin Bradford Rickerson, was theson of a Cheney mother and the nephew of Charles Oscar Cheney, who married Laura's sister Ada Minerva Hungerford.
1.Caleb Cheney (1771-1845) m Rachel Raven (1791-1839)
1.1Charles Oscar Cheney (1828-1904) m Ada Minerva (aka Minerva Ada) Hungerford (1831-??)
1.2Mary Bradford Cheney (1814-1891) m John Rickerson (1808-1891)
1.2.1Austin Bradford Rickerson (1833-1868) m Laura Hungerford (c1836/40-??)
An obscure point, I realize, but interesting to me, as I am related to the Cheneys in my paternal line and to the Hungerfords on the maternal side.
