I am trying to find out some more information regarding Leticia and Samuel McKee of Wolf Creek Twp., Mercer Co., Pennsylvania, Leticia was the daughter of James and Jane McKee of Slippery Rock Twp. Samuel was born about 1814 in Ireland, Leticia on 25 Dec 1814 in Pennsylvania, probably in Slippery Rock Twp. They had five daughters: Jane Helen, born about 1842; Roxanna, born about 1844; Caroline born about 1845; Adele Eliza born about 1847; and Olive, born about 1852. I lose track of the daughters after the 1870 cenesus, and of the parents after the 1880 census. Any suggestions appreciated. Thanks.
