There's a major inconsistency between the past thread of PoS and the end
of The White Rose, in that PoS portrays Doratea Senjack as having died
and never properly recovered from that, remaining in the Ghost Country
thereafter, while WR has Naming the Lady as Doratea Senjack as being
effective.
If we treat WR as a reliable narrative, then the key to the problem is a
quote from Soulcatcher On p. 164 of The Black Company:
"Didn't you know that she murdered her twin sister when she was
fourteen?"
I think that was a cover story, and in fact, the whole of the past thread
of Port of Shadows is the details of what happened behind that cover
story. However, it has elements of deception, being another layer of
cover story. It goes like this:
Credence and Doratea were the two younger Senjack sisters. One of the two
older sisters became Soulcatcher. Credence is the one who was actually
killed and imperfectly resurrected, Doratea is the one who went looking
for her, found her, was taken to the Ghost Country, came back, became The
Lady, and did her best to confuse the issue of who was who. All the
details of the necromancer, life in the Ghost Country, and so on
ultimately come from her, and may be part of the deception.
