The Luke Prior Allphin your are asking about is actually the son of William Allphin and Seneca Louvisa White. He was born 23 Apr 1825 in Marion Co., Indiana and married Amanda Points on 22 Sep 1847 in Schuyler County, Illinois. They had two children Lieucretia Calista Allphin born 12 Nov 1848 in Schuyler Co., Illinois and a son Oliver Perry Allphin, born 17 Mar 1851 in Schuyler Co., Illinois. Amanda Points died 12 May 1853 Schuyler Co., Illinois and Luke Prior married Sarah Harrington on 7 Dec 1853 in Schuyler Co., Illinois. They had three children Mary Elizabeth 23 Feb 1856 Schuyler Co., Illinois, Margaret Malissa born 22 Feb 18, Schuyler Co., Illinois, and Francis Columbia born 1 Aug 1861 in Schuyler Co., Ill. Luke Prior died 20 Mar 1908 Camden, Schuyler, Illinois and Sarah Harrington Allphin died 17 Apr 1915, Camden, Schuyler, Illinois. Hope this helps.
