I'd be interested to know what part of the county this couple was in.
I'm researching the family of Richard Alfred Allen (1827-1910) in Ammon. He named one of his sons Richelieu, who married Cora Belle Coleman. The family is heavily intermarried with Colemans and Robertsons.
Allen's father-in-law, Watkins Turner (1800-1863) was married to Judith Mann in 1830, and his eldest daughter (by a previous marriage) married John A. Coleman in 1842.
These folks all lived along Wills Road just south of Namozine Rd. and appear to have been involved with Poplar Hills Methodist Church.
