Yes there seems to be a large gap in ages of Fredeirick and Marie, and can possible be explained by the fact that quite a few ages were guessed by the ships Booking office, but it also was not uncommon for the woman to take a younger man.
A lot of the Info can be gained from the previous posts and I can forward you a copy of any Information I have sent the other two, where shall I send it?
