Harriet Amelia Wight
The inscription on her gravestone shows her name as "Harriot Amelia Wight, Wife of Ralph Jenkins," born 4 March 1849, died 27 January 1866. The problem is that FamilySearch shows her marriage date as 1 February 1866. It is possible that this marriage date is incorrect. The gravestone appears to be very old, so it likely has her correct death date.
