I'm wondering if what you are trying to say is, "Ia alofa aku fo'i isi o'u uso (rather than US) ma kmaiki ia ma oe le faletua". If this is so, then it translates thus: "Love too to my brother (assuming it's a guy who's talking) and children and you the wife".

"Manuia le taeao, la'u pele." As there is no word for lover in Samoan, I have translated the idea by using the word "pele" (dear, dearie), as it is an endearment.
"Manuia le taeao, la'u uo" (Good morning, my friend) or "Taeao lelei, la'u uo" (Good morning, my friend).
To say "happy 21st birthday" in Samoan, you can say "Manuia le 21 o le aso fanau." This phrase conveys your wishes for a joyful celebration of the 21st birthday. If you're addressing someone directly, you might add their name for a more personal touch.
Sorry, this is not a Samoan phrase.
