I wonder if any of the Dutton descendants might share, if known, the cause of death of Henry and his youngest daughter Martha.  It is curious that Martha died on June 25, 1851 and her father, Henry, two days later, on June 27, 1851. - - - - - - - - - - Sherry, Not to suggest anything positive but the country experienced a severe Influenza epidemic in 1850-51. It's possible they succumbed to the effects of that. Bill Brown
