Assassination Trivia

[L Verge]

I am calling this a trivia question, but I don't know the answer to it: An online source relative to Kate Chase Sprague says that she was one of only seven women to attend Lincoln's funeral in the East Room of the White House - and she did this in her seventh month of pregnancy (coming out of her confinement period to be there).

Is there any record of who the other six women were? Any Todd family members? Any Cabinet wives or generals' wives?
