Per Tom Fetters: (This is a branch of the Fetters that renamed themselves Feather.
It begins in Huntingdon Co, PA with George Fetters (1745-1823) x 1770 Elizabeth Switzer (1749-c1826)
His son was John Feather (1791-1828) x Rachel (1790-) of Stark Co, OH
His children were Elizabeth Feather x Isaac Harbaugh Uriah R Feather (1821-1888) x 1847 Elizabeth Hall (1827-1896) of Canton, OH (a) Harriet Shore x Harter
Uriah had three kids Mary E Feather x 1826 John C Allen (-1890) Frances R Feather John (infant)
Mary had five kids but only two are known: John F Allen and Stuart Allen
So the statement you BOLDED is wrong."John Feather, grandfather of Mrs Allen, was a colonel of a regiment of militia during the war of the Revolution and he died at the home of his adopted daughter Mrs Harriet Harter." Well, they got the daughter right, but being born in 1791 makes it impossible for him to have been a colonel in the Revolutionary War.
You may want to put a codicil on the story that it is not entirely accurate.
