hi Dave; my gggrandmother is Lucretia Rideout b Harrison Co Ky (we think) about 1828. i am including notes from the one lead I have:
Lucretia married Cyrus DeMoss 8 Feb 1864. Their one known son, John McKinley Fletcher DeMoss (b abt 1865)was born in Metamora Indiana, apparently while the family was there temporarily. There is a William Allen Rideout who died in Metamora, Indiana 13 Oct 1869. He was born in Lincoln Co Maine. He married Eliza Baden (b abt 1820 in Ohio) 13 Dec 1838. Lucretia/Cecelia as either younger sister or early daughter to William would be workable date-wise. It is inconceivable to me that two Rideouts can exist in Metamora (max pop 450, now 125) and not be related somehow.
