I am unable to determine which Joseph Abney and brother James you are referring to.Who are the parents of James and Joseph?
My line starts with Martha Elizabeth Abney. She married John E. Davidson in Georgia in 1856. Her father is Absalom P. Abney, born 1803. Absalom's father is William Abney, born about 1777. William's father is Michael Abney, born in Halifax Co., Va. Michael Abney's father is George Abney, born before 1728 in Virginia. George Abney's father is Paul Abney born 1639 in England
