Checked my wife's Chisholm-Chisolm families histories. (S.C.) No marriages to a Davis, one , William Edings Chisolm b. l855 in Charleston, S. C. married in Richmond, Va. and died in Baltimore, he had one child, William Garnett Chisolm b. l890, Baltimore and was the author of the Chisolm Genealogy ,l9l4. These are the only Chisolms from my wife's family that were known to have lived in Maryland. Suggest you place your message again under Chisholm and again under Chisolm (same Clan, different branches keep dropping the 2nd h over the years) good luck!
