A number of family trees on Ancestry.com has John Hughey's parents as Henry Francis Hughey and Rebecca Belle Alexander. They have Henry born 1849 in Caldwell Co, Ky, died 1894 in Fredonia, Caldwell Co, Ky. They have Rebecca born June 2, 1855 in Grayson, Carter Co, Ky, died Mar 13, 1907 in Mancelona, Antrim Co, Michigan, buried in Fairview Cemetery. It appears that Rebecca remarried to Robert Barnett after John Hughey died. They have a photo of Rebecca's tombstone and it says Rebecca Barnett.
If you think that what I sent above is correct then they have the Hughey line back quite a bit farther.
