I am looking for the names of the children for Peter Duck (Dock) and his wife Mary Bricker (Molly). Peter was born on 15 Aug. 1796 and moved to Newville, Cumberland County in 1800 with his parents Phillip Dock and Elizabeth Killian. Peter Died on 15 Dec. 1841 and his wife died on 18 Feb. 1848. Both are buried in Prospect Hills cemetery in Newville. According to the 1830 census they had 7 children and the 1840 census shows 9 children. All children would have been born in Newville between 1821 and 1841. Any help will be appreciated.
