Could she have gone by the name "Mahala"? In the 1880 census, there is an Adam Jordan with an estimated birth year of 1824 (same as her husband Adam) and a son William (whose estimated year of birth of 1863, same as her son "Will").
I did not find any Find a Grave memorials that seemed to match Harriette (or Mahala), Adam or William. Emens-67 00:38, 3 October 2018 (UTC)
