Sorry, but this Daniel D Doolin is not the son of Archibald Doolin and Ruth Ann Thompson. Their son Daniel D married Rebecca Joiner and lived in Butler and Dunklin Co. MO. There is a Daniel Doolin age 25 living with Jesse Doolin age 31 and family in 1850 White Co.,IL, this maybe the Daniel Doolin you are looking for. Your Daniel D. Doolin served in the 81st IL and received a pension in 1866 and Emiline received a widows pension in 1896. D Doolin was in Williamson Co. IL in 1860 with Emeline, T.M. (male), M. E. (female) and Susan T. In 1880 D.D. Doolin is in Franklin Co.IL with Emily, Logan, Liza Jane and Ida Mary. His son Thomas Miles is also there with his family. It is very possible that Jesse and Daniel D Doolin are the sons of William Doolin and Sarah Vickery.Sarah a widow has 2 males the correct age in 1830 Fayette Co. IL. Sarah married Jonathan Green in 1834 and died about 1845.William Doolin is a son of Daniel Doolin/Doolen and Mary Bridges. Daniel Doolin/Doolen was an uncle of Archibald Doolin.
