My father, John A. Coram, is the brother of Ruth Coram. My information agrees with yours concerning their father, John E. Coram. The George W. Minor Family Bible has a birthdate of July 21, 1877, for Malinda, but the 1930 US Census (and earlier ones) indicates a birthdate in 1879 or 1880. John E.'s father, I believe, spelled his name Wrenford.He was born in England in 1852, moved to Canada in about 1854, and then to Missouri in 1868, along with his father, William G., brother, Alfred E., and two sisters, Amanda and Charlotte. Since these Corams did not come to Missouri until 1868, I do not believe they are related to the Corams in the original query.
