Oh, found another one! At least I think this counts,

In Greg's Williamsfort Gazetteer:

"Neg is the eldest surviving son of the Baron Carrion, the former Baron of
Williamsfort, still residing in the Kingdom of Blackmoor. His family had the
misfortune of backing the Thonians during Blackmoor’s War of Independence,
which many refer to as the Thonian Invasion. Many of the Carrion family died
fighting for the Thonian Empire during the war. "

Working on some timeline stuff and its been forcing me to think about Baron Jenkins and Fant.

Here we have them listed as houses, but there are a couple problems doing that.

The obvious one is that in other cases, we use the baron's first name - for example, Baron Alvarez, Baron Calvin and so on. We never say Baron Andahar.

So theoretically, it should be Baron Jenkins of house x and Baron Fant of house x, etc.

Here is the other thing. Jenkins was, from the start, in control of Glendower and the surrounding land.

If you look at DA1, the description of the Baron of Glendower really sounds a lot like Duane Jenkins and his character. There is even the bit about being bitten by the undead (a lycanthrope in DA1, but a vampire in the original campaign).

DA1 clearly has a lot of name changes, and they all do have a kind of similar style, which probably means they were done by David Ritchie or somebody at TSR. I think "Bascom Ungulian" was an editorial change to Jenkins. The other thing to note is that the Ungulian family has had control of Glendower for some time.

In any case "Jenkins" makes more sense to me as a first name, and that would apparently make him an Ungulian - presumably the father of Bascom.

Same reasoning applies to Fant.

When the elves take over Blackmoor castle after the second Coot invasion and the invaders are defeated, CoTT 4 #6 says Fant "has returned to Bramwald".

So apparently Baron Fant was from Bramwald. Sometime not long after his return there he becomes the Vampire Sir Fang.

The Baron of Bramwald in DA1 is given as Bram Tagus. So I think it makes sense to suppose that Baron Fant was also a Tagus.

Something to consider anyway.

Good points, although keeping all the pieces together may be not the easiest puzzle to solve.

Some more to consider:

"From Lyliania's diaries, Jezyria also learned of
her engagement to Laurent Kervall, a noble who
assisted her father at court" MMRPG - Lord Braveen is the father mentioned and that's Blackmoor court so Kervall must be a lesser house in service to Braveen.

There is also Baron Von Hercebeiner from David Megarry's character sheet. Von was a Blackmoor baron who died exploring the New Lands (Outdoor Survival board) in late 1972. Von had two sons who died the same way, all in quick succession.
