Marriages found in Jefferson Co, IL for Henry Moore:
MOORE, HENRY ROBINSON, SARAH 1844-12-26
MOORE, HENRY P LAND, MARY O 1858-12-15
MOORE, HENRY P GADDIS, MARY 1876-12-12
It appears Sarah Robinson was his first wife and she died 4-12-1858 according to gravestone at Green Cemetey, JCI indicating she was wife of H.P. Moore
Mary O. Land appears to be his 2nd wife and she is also buried at Green cemetery with gravestone indicating she is wife of H.P. Moore
Mary Gaddis appears to be 3rd and final wife and she is not buried at Green with any notation of being wife of H.P. Moore.
Ella could not be the daughter of Mary Gaddis since she was born before Henry married Mary Gaddis. Mary O. Land must surely have been her mother since she died in 5-6-1876.
