The information that I have on James Evans siblings doesn't list a Phoebie Evans b. 1791. Andrew Evans and Elizabeth Fain are suppose to be James Evans parents. James was born in Kentucky and he married his wife Sally Garrett Aug 18 1818 in Warrick County Indiana. Do you know where your Phoebie was born or where she was married? Do you know where her husband Jesse was born? Was she and her husband living in Warrick County before 1875? I didn't find Jesse and Phoebie in the 1850 or 1860 Warrick County Indiana census. There was a couple of other Evans families living in Warrick County also. I don't know how or if they are related to each other yet. Sorry I have more questions than answers for you at this time. Let me know the other dates you might have for them and maybe I can help help you figure out if she was related to the other Evans families of Warrick Co. IN.
