From an Email from Cheryl Chatfield (who created the Chatfield Section on OxfordPast.net)
His wife: Mary Elizabeth Seymour Chatfield: I had discussions with my great-aunts because they always called her Elizabeth and they did not believe her first name was Mary. Beecher called her "Lib".
See Cheryl's picture of Elizabeth Chatfield here.
There is and interesting letter here from Beecher Chatfield to William Seymour, Mary's father, written during the Civil War.
