There are 2 Ephraim Sharps in NE Arkansas in the mid 1800's.
I think you want this one: Ephriam SHARP b 30 Jul 1815 OH, Hamilton, Butler Co, USA; d 17 Nov 1898, AR Lawrence Co USA; buried Hibarger Cemetery , Strawberry, Lawrence Co USA
His third wife (married 19 Jul 1858 Lawrence Co AR)was Elvinia GODWIN 1832 IL - 18 Dec 1872 AR
children: Margaret Amanda SHARP 1863 - 1916 +Pinkney SHIPLEY Mary SHARP His 4th wife was my great great aunt Nancy Croom.They died within a few days of one another.
Ephraim was a farmer, State Representative, Physician-listed in the census.I've not found a descendent that knows he was a physician.One noted he helped Doc Croom.I assume Millard Filmore Croom his son-in-law and Nancy's youngest brother.There was also Hiram Croom, my gr grandfather, who was a doctor.
