They choose to make her maiden name into a middle name for all their children. The next step was to combine both of these names into a hyphenated last name and thus the creation of a new surname.

Another last name change occurred when their eldest son changed his last name to Slott-Nielsen. His dislike of Sloth was found to be embarrassing, especially if mispronounced (slof and not slot) and in the definition (laziness and a slow-moving mammal).
