Honestly, I almost guarantee Anastasia is NOT the Kerensky Bloodhouse leader. First off, she came from the Exiles and wasn't particularly popular there, hence her escapades that brought her into the Republic space in the first place. Second, Bloodhouse leader is a very political position, and Anastasia is not fond of politics. Third, according to The Clans: Warriors of Kerensky on pg 97, Each Wolf Clan had its own set of Blood Heritages and Bloodhouses, meaning double the normal count.
One last thing to remember is there are two Kerensky bloodnames, thus two separate Bloodhouses.
Except . . .
#1, where we have seen it the highest ranking/prestige bloodname holder is the House Leader . . . the only exception I can think of is whatisis Pryde that was CO of the Falcon Guard while Marthe Pryde was Khan- BUT he had the Aiden Bloodheritage which the Falcons were still swooning over. FREX, after former Khan Cyrilla died it was Conal Ward IIRC until Phelan became Khan and Conal was ousted the same day.
#2, Anastasia could have the position and delegate much of the duties/responsibilities . . . with that said, during her time as saKhan the touman did not suffer under her management. So she can either do it or can find people to do a lot of the admin stuff for her.
#3, I would say that phrasing is actually suspect as indicated by FMWC later. The Warden Wolves left with a full copy of the genetic repository. However, if they did not have a Bloodname holder go into exile with them they did not fill or even use those Bloodnames maternally. FMWC indicates they had a handful of dormant Wolf bloodnames because of this situation. We have also never afaik been given a indication the Wardens expanded beyond the Bloodname count they left the OZ with- nor that the Crusaders appropriated the heritages of those who went into Exile. The ONLY case was Phelan's Ward heritage which is what everyone assumed Vlad was fighting for, but he claimed Conal's vacant heritage.
I take it back, the Wardens DID use one Kerensky Bloodheritage that did not arrive in Lyran space- Natasha's heritage that Ranna took. We do not even have any indication they 'used' Ulric's heritage going forward.
The Crusader Wolves in the few interactions we get between them and the Wardens outside of Phelan/Vlad show respect between the warriors and recognition of their Bloodnames as legitimate. When Alaric temporarily seized the Warden observer before they turned on the Lyrans, he was given the honor of his Bloodname and invited to return. Alaric's general call for them to return also did not indicate they were viewed as a separate Clan. He also recognized the Warden Wolves' resurrection of Jaguar Bloodhouses, letting the a Weaver fight a Trial of Propagation that was won . . . though the Crusaders had no access/control to the legacies at that time.
Finally, while we know there is A Kerensky and N Kerensky Bloodhouses the writers have never told us which one any of the named characters.
As said before, it is unfortunate TPTB have never delved into the Bloodhouses or their politics because it is the underlying foundation of all of the Clans politics. I do not expect that to change and there is a chance this could get handwaved where the Bloodhouses are consolidated after the ilClan Trial and as part of the victorious side have their Bloodname counts expanded to 50 possible if they were all propagated or at least the count as of the time of the landing on Terra. IE, say between the two Clans there were an active 38 Wards or whatever. This recognizes that most Bloodname counts would not have been at full count anyway.
