Once upon a time, there was a castle on a square island. The entire island was surrounded by a 14m wide trench.

The Romans still managed to cross the trench. How did they do it?

There were two grandmothers and their two granddaughters.
There were two husbands and their two wives.
There were two fathers and their two daughters.
There were two mothers and their two sons.

All are born legitimate and relationships clear.
