I'm stuck here too. I did the "All in the Family" quest early on and no longer have the "Bloodmoon Island Archives" (probably sold it wayy earlier). I've learned that the ghost of the archivist will tell me the trees name, but that never comes up in our conversation. Sooo how am I suppose to learn the trees name? I've also talked to the two remaining spirits including the Elven Druid (I killed everyone else) and they don't give me the name to advance the quest.
Thanks!
"Blood Island Archives" is supposed to be the Archives which is underground below a hatch (north corner), not a book. The book you need to read is the Archivist's Journal, which is in the Archives.
