I'll give you what I've got which isn't very much. My line is actually the Pinnells.
Andrew J Pinnell m. Eliza Ann Poulter in Edgar Co IL Jan 17 or 20, 1842. I suspect one is the marriage date, the other the registration date. Source:http://www2.sos.state.il.us/cgi-bin/marriage
They are shown on the 1850 *COLES* Co IL census, ages 29 and 27, with their two children James H and Winfield S. Interesting that Eliza Ann's birthplace is listed as Miss. ??
On the same page of this census is another young family. John D Poulter age 25 b VA, Mary D age 20 b IL, Mary A age 1 b IL.
Also on the same page of this census, Henry H. Pinnell age 34 blacksmith b KY, Minerva age 18 b IL. I know a Henry H Pinnell married Mary A Poulter in Edgar Co, IL in 1847. Don't know if this is a different Henry H or if Mary just didn't get counted for some reason.
There are also many Poulters on the 1850 Edgar Co census in Grandview and Embarrass District. This is where many of my Pinnell and Atkins ancestors lived. Included is a James W Poulter age 34 gunsmith b KY and, among others, his daughter age 5, Sarah Jane.
Hope that is of some help. I would very much like to establish for certain who the parents of Eliza Ann Poulter were. Poulters and Pinnells married each other right and left ;-) and I would love to fill in the gaps!
