In fact, these are the 12 sons of Jacob. Joseph was never a tribe, his sons, Ephraim and Mannasseh, were tribes. Levi wasn't a tribe either, but rather the priestly caste.
Missed the three least guessed which were also the three hardest to spell - maybe a correlation? Although in my case it was just poor memory. I kept trying to include versions of Joseph's sons, thinking they were names of his brothers. Time to reread Genesis.
