I used to be a big fan of Don Rosa and his duck comics as a kid.(Life and times of Scrooge McDuck was a great series!)
And i remember a family tree he drew to show all the relationships between the characters.
Well on the tree he left the father of the young ducks blank with a note saying he would reveal it in the future and that everyone would be surprised by the revelation.
Was it ever revealed?
For some reason i must resolve this open thread from my childhood 
Now, that’s obscure. Do you remember who their mother was? That might help remind people.
Yes i think it was Della Duck,the sister of Donald.
What jogged my memory was reading this thread : http://boards.straightdope.com/sdmb/showthread.php?s=&threadid=129495&pagenumber=2
I’m hoping Octavia will read this thread,as he seems to know his stuff.
The family tree was printed in Walt Disney’s Comics and Stories #600.
I don’t know if he’s written that story yet. Are they even publishing Disney comics in the States anymore? I know that Gladstone stopped publishing a few years ago (right at the time my subscription was about to lapse) and they said that a company called Gemstone was negotiating with Disney for the rights. Apparently the nogociations were tough, and I never heard that they managed to hammer out a deal.
It’s possible it’s been published in Europe, but, unfortunately, I’m not too up on European comics. I know that Rosa works (or did work) for Egmont, in Holland, though. All his stories are published in Europe before being published anywhere else.
Don Rosa! Damnit. I’m not going to get anything done tonight, 'cos I know I’m not going to rest until I can find where I stashed all of my Disney comics from the 80s and 90s.
Della Duck appeared in the flesh (feathers?) in his Life & Times of Scrooge McDuck. Her husband was never named, but was hinted that he was a brother of Daisy Duck.
But that’s like asking the square root of a million – no one will ever know.
1,000 is good enough for me 
Well after a little digging on google i have found that the consensus is that it is Daisy’s brother,even if it is never explicitly said.
Loopus: I have no idea if they are still being printed in the US,last time i ever saw them was around 93 i think and i just assumed that disney or whoever had shut down the comics division.
You mean Don Rosa is still producing comics,but they’re not coming to the US?
Huey, Dewey, and Louie always referred to Donald as “Unca Donald.” So he ain’t their father.
From a timeline I saw on the Net, Rosa seems not to be working regularly, but he does do special stories with the Duckburg citizens for Europe every so often. And of course, the Duckmeister, Carl Barks, is dead. So we may never know.
Here’s a page you might be interested in, effac3d: The D.U.C.K. Man. It contains a lot of info on Rosa, and even has some of his stories scanned, including a new chapter of The Life and Times of Scrooge McDuck from 2001.
Since it was never printed in English, the scanned version is (badly) translated from the French version.
Rosa is still working for Egmont, as far as I know, so Europe has first dibs on his work. Since I don’t think they are publishing Disney comics in the US anymore, he is, indeed, producing new work we never get to see.
…and where does it leave us with Daisy’s nieces, April, May and June that Huey, Dewey and Louey are always forced to dance with at social functions?
Here’s a somewhat poor quality scan of the Duck family tree – if you know the name you’re looking for, you can make it out. This is the one from Walt Disney’s Comics & Stories #600.
April, May & June’s mother:
Here’s the webpage of Gladstone Comics, the last publisher of Disney Comics in the US. Their latest “news” on the matter of ever publishing them again is from Fall 2001, and is this:
I don’t recall reading anything in the stories that revealed who H, D, & L’s father is, and as you can see from the other’s posts, it would seem that is going to be one of the mysteries of the ages (at least as far as how Carl Barks would have arranged things).
I’m intrigued by Barks’ comment that we’d be surprised by who their father is. racking brain to think of the possibilities
I am certainly not a Duck expert (but thanks for thinking it). All I know is what I learned reading the comics over and over again with my dad and my brother. I’m pretty sure I didn’t come close to reading all of them either. O’ happy thought - the tales that await me!
I’m sorry to hear that they’ve stopped producing the comics in the US. Not so very long ago, my brother bought several reissued versions of some of the most classic Barks’ stories with cardstock covers and vibrant color pages. IIRC, they may have even featured an ad for Sea Monkeys or possibly a way to earn cash, prizes, and a feeling of accomplishment selling Grit magazine.
Oh, and effac3d, as this is a board designed to fight ignorance, my sense of duty requires me to inform you that I am a girly-type humanoid. (Absolutely no offense taken, however.)
