Hi...Why does it have to be a poem, not that I don't love poetry, but your heart family are individuals, each different, and I am sure there is something you love about each. May I suggest you buy some extremely nice stationery and sit down and write them each a heartfelt letter containing in it, those qualities about them that have enriched your life? There is nothing quite like receiving something hand-written, old-fashioned by today's standards, but nonetheless, elegant, and meaningful. You could do a very small poem, perhaps two stanzas at the bottom that would be to all, but this is way you love to each is personalized. Just my thoughts on your dilemma. Good luck.
