I'm not sure if you are looking for relatives to add to the tree, but if you are, here are two that I don't think you have on there (though you might, I didn't see them when I looked at your tree, but I could be wrong) Uncle Sven and Aunt Greta. They are from this book: Lapland Friends: An Adventure in Sweden. On my Duck family tree, I had Greta be Grandma Duck's sister, because they look alike, and because HD&L mention that Grandma Duck told them about Greta and Sven.

That's definitely interesting, and I do want this tree to be as complete as possible! However, if I do have them in there, I would have Sven and Greta be much more distant cousins. With such names, they sound like their were born in Sweden, don't they? And in this 2013 story, we see Grandma's (explicitly distant) cousin who lives in Finland, called Martha. So my theory would be that Sven, Greta and Martha all belong to a particular branch of the Gadwall family who moved to Scandinavian regions at some point in the 19th century. On the question of whether they're distant enough that putting them on the tree is impossible or not, I'll have to think about it some more.
Thanks, anyway, though. And you should probably create pages on the Wiki for Sven and Greta (and for An Adventure in Sweden itself; as it happens, I created a Storybook template just today, you can see it on the Jasmine's Royal Wedding page).
As stated by Jano Rohleder, German publisher of Don Rosa and operator of his Facebook page, here, James Duck is actually not HDL's father from Rosa's perspective. He, according to Rohleder, made that unofficial family tree for a friend/fan and drew the face of said friend in duck manner. I think therefore that in this regard, you should add that this is NOT the father who went to Xanadu, but just a gag for a friend. Here is Rohleder's full post translated into english:
The user ScroogeMcDuck from the English Disney forum "The Feathery Society" has put together a very interesting family tree in which the father of the triplets a certain "James Duck" is specified. The following note can be found under the tab "Biographical":
"HDL's ever-unseen father, Tralla La at some point by Don Rosa in unpublished sketches for" Return to Xanadu ".
His face is drawn to Mark Worden's Duck Family Tree, and Don Rosa is therefore included in an unofficial alternate verison of his own Tree that includes Ludwig von Drake. The image comes from a drawing he gave to a French fan at a convention.
Due to a misunderstanding, the rumor once circulated on French forums that Don Rosa had christened the character "Jamie Hawkins Duck" ("Jamie Hawkins" is actually the name of the fan of the unofficial tree belonged to). As a result, James has remained the character's unofficial first name. "
This is nonsense. This family tree was a commission for a friend / fan and the face to be seen there was the same person. Don has deliberately NEVER drawn his father because he felt that was too much responsibility.
The forum guy puts it here as if that's what Don would have liked to do, but just did not want to do it officially, and so on, but that's not true. That was just a gag for the one who commissioned it. Don also used this drawing as a print at conventions and removed the person's name. In the corresponding text box he now writes - also as a gag - the name of the purchaser of this print.

Ugh, I think we've all got some things confused here. That this picture:
might be a caricature of one of Rosa's friends, and not at all a serious rendition of "Mr Duck" (James or otherwise)… that, I'm willing to believe, in hindsight.
Note that it doesn't invalidate the idea of the name "James" as such, though, since not only do I already acknowledge that it's just a fan thing based on a mistake, it's wholly unrelated, since it comes from a print of the family tree.
When you look at the unofficial version of the Duck Family Tree,
…you can see something that I must admit I failed to notice: aside from a superficial resemblance in the haircuts, this Mr Duck is wholly different from the above not-actually-Mr-Duck.
The blank-name-filled-in-with-the-name-of-the-fan thing may be an in-joke, but it's a completely different in-hoke, and it'll be hard to convince me that this face is not what Rosa thinks might well be the face of the real father. Especially considering that it looks to me like a very direct Don Rosa rendition of the face of Mr Duck in the Mark Worden Duck Family Tree:
Same haircut, same shirt collar. To me it's clear that this one is an actual rendition of Mr Duck, not the caricature of a friend.
And to be clear, again, the "James" moniker (inasmuch as it ever had the tiniest shred of official support) was initially tied to this one, not to the one with the tiny eyes and the bowtie that you now reveal was just a caricature.
