The two names Emily and Luther Elizabeth do not many any thing to me right off all though they are probably a little later than I have traced descendants.
Richard Byrd (1750-1803)left a will in Hawkins County, Tn signed by him in 1803. In it he named his wife Elizabeth (Buster born abt 1750-died abt 1815), his children William (a minister in North Al married Lydia Adair), John, David (m Jane Moorehead), Jane/Jean (m Randolph McDonald, Ann/Nancy (m David Day), Michael (m Patsy Logan and Jane), Richard, Elizabeth (may have been the Elizabeth who married Jonathan Adair Burleson), Mary (m James Worry and Daniel Walsworth), James, and Charles.
Elizabeth is thought to have brought her children into NE Alabama after her husbands death.
