@Therahedwig - Most likely, yeah!
On another note, I have just gone through the entire royal lineage of one of my civs. I am very happy to see that now it seems royal succession seems a bit more consistent than before. In this particular civ, every one of the royals I got had children and except for one case they passed the throne from parent to child. The one case in question is actually King Asėn, that I wrote about earlier. But in his case I was even more impressed, because he survived all his kids, but then his grandson, King Tekkud II, assumed the throne after him. It seems that dwarves are finally preferring the royal line with a good degree of consistency now! In older builds I remember that if a King died without an immediate child, the crown simply passed to some other rando with no degree of relationship to him and most of the times no obvious reason why they were chosen. Now it seems things are more consistent. This particular lineage of Kings has been extent and unbroken from game start till the year 550, so it is pretty consistent.
Another civ I was monitoring also had a consistent lineage right up until their last Kings died just 13 years after assuming the throne, killed in an invasion and impaled on hazel wood pikes. After that the crown was passed to a rando called King Datan. But the interesting thing is that while the first royal lineage lasted there was no coups or any attempt at dethroning them, but as soon as the rando appeared we got a coup. King Datan was dethroned after 59 years in power by a group of Goblins being supported by some dwarven colaborators. Now here's the interesting part: When that goblin Queen died in battle, the one to assume the throne was the nephew of the deposed random King. A guy named King Olon. But get this, he was deposed by the same faction that deposed his uncle. And the faction leader this time decided to crown himself King (he was a goblin too). King Atu. After that King Atu suffered a coup by a relative of his called Dang, and Dang put King Atu's grand-niece on the throne, Queen Ngom. Then Dang did a coup on her and made himself King. All in all, this all feels very Game of Throne-y and you can feel the family intrigue happening. Might be just coincidence, but it does feel like Dwarf Fortress is a lot more aware of familial relations.
