Tried to email you, however for some reason, I cannot email to people with AOL.
The Elizabeth SLOAN you mention in your query is not a SLOAN by birth, she is a HALL, she was married to William H. SLONE (brother to my ancestor). I believe they may have divorced as she remarries in 1875 to Thomas TRUEBLOOD. She (as Elizabeth Trueblood) and her children are mentioned in the 1880 will of William's father, William SLONE 1801-1880.
I have info on your HALL/SLONE families to share, just have to figure out how to get it to you if I cannot email to AOL. Would love to have children for Thomas TRUEBLOOD and Elizabeth HALL, also ancestors for him, as the TRUEBLOODS marry into a few of my families of Madison County. Thanks .. Karin
