Mary heard that David Livingston had died and she knew she wanted to assist in the work of God in Africa. Soon thereafter she boarded an ocean liner.

Her denomination in Scotland, the Presbyterian Church, did not allow women to preach.... unless they did it far away. :)

There are a number of statues of her in Scotland and Nigeria. She is depicted holding two precious African children. She had taught the natives that twin children were a blessing and not a curse.
