When Mary was three years old, Godwin left his daughters in the care of James Marshall while he travelled to Ireland. Godwin's tone in his letters demonstrates how much he cared about them. His letters show the stress he placed on giving his two daughters a sense of security. "And now what shall I say for my poor little girls? I hope they have not forgot me. I think of them every day, and should be glad, if the wind was more favourable, to blow them a kiss a-piece from Dublin to the Polygon.. but I have seen none that I love so well or think half so good as my own."
