Looking For Death of Elizabeth Beard nee Arms in Bedfordshire England.
Elizabeth wife of Samuel Beard mar 10/9/1788 . They had one son Joshua b 7/10/1789 in Haynes(Hawnes)
Have been unable to find this death as there are so many Elizabeth Beard deaths on record. I assume as only one child they either divorced of Elizabth has died early.
