Warriors of the Clans.
You mean The Clans: Warriors of Kerensky
I think specifically its the Clan Wolf (and Exiles) writeup section from memory.
Found it (DANG! it's been a long time since I checked the old writeups in WoK!); pp. 97:
"Both factions have complete copies of the Wolf Clan's genetic legacies and have pursued their own eugenics programs. Both have also held their own Trials for Bloodheritages, resulting in the existence of two holders of each - one Crusader, the other Warden. Unofficially, the Wardens have shown a willingness to arrange Trials only for the heritages they took into exile."
One could assume that said trials take place only once the current living holder dies. In the case of WiE Jane Kerensky, while she lives, she is the only holder of that bloodright; however, when she bites the big one, two Trials of Bloodright will take place; one among the crusaders, one among the exiles. Interestingly enough, if Crusader Wolf Daria Kerensky kicks it, only one Trial of Bloodright will take place (among the crusaders)... at least according to WoK (around 3062); there is no guarantee that the exile's willingness to refrain from doubling crusader Wolf legacies extended beyond that year or Kell's tenure.
Interestingly enough, the WiE Khan could institute a Trial of Propagation to make use of abandoned heritages which the crusaders are not using; particularly in Limited Bloodnames like Conners, Shaw, Ch'in and Leroux (which have five or less legacies among the crusaders as of 3085).
Of course, the exiles have Kell plus any "Dragoon" legacies (IIRC they had instituted a bloodname-like practice and had their own eugenics program). They might also have access to the Nova Cat eugenics program, which would certainly help maintain "purity" in both trueborn programs.
The exiles might also have "free access" to the DNA and bloodheritages of any warriors (or even ex-warriors under certain circumstances) with legacies from the "dead clans".
Regarding the thread's topic; since the Homeworld Clans decided to close communications with the
tainted Inner Sphere Clans (not abjured; that requires a Trial), they would be unable to use the DNA or bloodname, since they would be unable to Trial for their use... HOWEVER, they might be able to use the legacies of those Kerensky warriors still in their control (i.e. abthaka) IF those legacies can be traced back to the WARDEN Wolves-in-Exile who were fully abjured by the Clans as a whole and by the (legitimate) crusader Wolves.
This might bring about the extraordinary situation that for a few particular Kerensky legacies, there are THREE holders of the heritage! To continue my example, when WiE Jane Kerensky kamikazes into a fig tree, the WiE have a Trial of Bloodright for her bloodheritage, the Crusader Wolves have a second Trial of Bloodright for her bloodheritage and when word of her death reaches the Clan Homeworlds, a THIRD Trial of Bloodright takes place for her bloodheritage; the competitors are her sibkin Joe (captured by the Cobras) and a bunch of warriors created by the Scorpions from her abjured DNA. The winner of this Trial would be the Head of House Kerensky (Andery) in the Clan Homeworlds; his/her matrilineal descendants, as well as those of the other (legitimate) competitors sharing his/her matrilineal DNA (Andery Kerensky's) would be able to compete for new bloodheritages... including other Andery Kerensky descendants captured from the Crusader Wolves.
Thus, there might potentially be as many as 150 Kerensky bloodnamed warriors (assuming something similar happens with the Nicholas line), but the probability of this would be so remote as to be nearly impossible. At best, you might have Kerensky (one or the other) with a few legacies in the Clan Worlds, 25 of each among the Crusaders and unusual numbers up to 25 each among the exiles.
