Thomas Evans, vous fera m'épouse
Thomas is pronounced the same in French as it is in English.
"would you marry me" is "voudrais tu m'épouser ?" in French.
"... t'épousera"
se marient déjà
Joyeux Noel is how you say Merry Christmas in french.
You would say "Je veux me marier avec toi" in French.
je veux me marier bientôt.
oui oui, you haz bootiful child, i wish to marry
"Nous espérons nous marier"
The book doesn't actually say who Dean Thomas ends up marrying.

The same as in English/Italian, if you are referring to Thomas Jefferson's house.
