It looks like William Humphrey Jones has gotten an extra wife and children.
He was definitely married to Mary Lucy Harris (Lucy Jones).
Three children by Mary Lucy are noted on her FindAGrave memorial:
Mosias (Mosias Jones)
Elizabeth (Elizabeth Hern)
Richard (Richard H. Jones)
... and their dates are consistent with Mary Lucy's age at their births.
However, many of the other William Humphrey children could not be Mary Lucy's children.
Nor, if the marriage to sister Mary Sarah Harris (Sarah Jones) is in error (as it may be, since she died before the claimed marriage date with William Humphrey), would they be children of Mary Sarah & her husband James Martin.
So, I think the marriage of Mary Sarah to William Humprhey should be removed.
Where do all those other Jones children belong?
(Probably to another William & Mary or two or three which got smurged in over time.)
