experts agree that the name is Dutch or German, but they seem to
disagree about its original form. Some say Everard, some say Eberhardt,
and still others, Everstyn, Evertmann, and more. In the
Massachusetts Bay colony of the 1630s the name was Evarts. Like so many
others, the name changed over time, with different branches
using different spellings.
Perhaps best known in this country was William
M. Evarts, Secretary of State under Rutherford B. Hayes, and, when in
Congress in 1868, one of the counsels of President Andrew
Johnson at his impeachment trial.
