John, I do not know about the background of the John & Elizabeth Beard.
There has been some mention that he or his father came from either Ireland or Scotland.Some researchers say through PA or VA; however nothing that we can say for sure.
I know of only 3 children: Martin H. Beard b 1831 married Emaline Hutto Huldah Beard b.1832 married William Hutto (Emaline's bro.) Martha Ann Beard b.about 1835
I feel sure that the line I am trying to follow has more sons.Too many "Beards" living in the same areas, traveling the same paths; yet no linking relative.Also, from copies of pictures there is a striking resemblance in several lines; black hair, fair skin, light colored (blue) eyes, etc. It has been suggested that there is Cherokee in the blood line.
