@jeupke,
Prospatia est meus pectus pectoris --> Family is my heart
Prospatia -- I am not familiar with this word and could not find it in my
Latin dictionaries.
pectus pectoris -- Lierally this means "breast of breast". Figuratively, it
may be a way of saying "heart" as the seat of affection.
Familia est omnia --> Family is everything
Looks OK to me.
Vivat, crescat, floreat --> Live, believe, bloom
This means "Let it live, let it grow, let it bloom"
Quia amo valde amo et foveam --> Whom I love and protect
This means "Because I love greatly I love and cherish"
