Does what you have contain more about the family of Walter Alexander and Catherine Jolliff??They are my direct line.
I have Elisabeth Hartline's book, "The Jolliff Family History with Rheas, Faulkners, Holstlaws, Alexanders".
Elisabeth Hartline sold her book privately. I bought my copy in about 1982 by writing directly to her.Unfortunately she is now deceased.
Much of the Alexander family is very difficult to trace, especially Walter. Since he and Catherine both died before 1850, we only have from a daughter who lived until after the 1880 census the indication that her father was born in Kentucky.No idea which county though.
