Hello Maxine. I think you will find Rootsweb of some help. Go to MetaSearch and enter the names Henry Abney. You'll find info there on both of his wifes. It might give you a lead. They have: Henry ABNEY, b. 18 Aug 1809, Jackson Co., TN,d. 1856, Saline Co., IL. Mar. 1st wife, Jane Carson.
I'm researching Henry, who is my 2xG grandfather through his 2d wife, Mary Howe (who I'm guessing was Parmelia's sister, since they were two years apart and appear in the 1850 Saline Co., IL, census under the same household). Hope this helps. Good luck. Justin
