Thanks for the follow-up.James H. Dossett (b. 1822) of Hardin Co. named two sons Ille;one Ille Dossett and one William Ille Dossett.James and his wife were from Tennessee and most probably related to a William Dossett who appeared in Hardin Co. around 1830.The Lincoln Co. census information suggests, or at least makes possible, the conclusion that William and James H. Dossett were brothers.The Elbert you mentioned from Tennessee was born in 1831 and is almost certainly the brother of James H.
The Forrester connection comes from Mary Drucilla Forrester, sister to the Ila Forrester you mentioned, who married a William Dossett in Orange, NC.Another tantalizing link is a Drucilla Dossett in Hardin Co.She is believed to be the daughter of the William Dossett who arrived in Hardin at or after 1830.There are three young Dossett girls who appear orphaned living in other households in the 1850 census. One is living in the household of Abner and Sarah Barnard.Sarah, born in IL in 1827 (according to the census), carries the maiden name of Dossett.
The working hypothesis is that William, James H. and Elbert Dossett of Hardin Co., IL are all sons of the Ile/Ila Dossett and Polly Holland of Lincoln Co.Sarah Dossett Barnard may be their sister or some other close relative.It this is true, then the William Dossett in Campbell Co. may not be the William who married Drucilla Forrester.What we need is more information from or about the Lincoln Co. Dossetts before we can firmly establish the connection.
