While aggregating some genealogy data for my family, I recently came across something that has my daughters and I pretty excited. It would seem that, on my wife's side, there is a traceable lineage to a member of the Royal Family of Denmark. (In the early 16th century, not the current family.) I found this in two separate sources, so even if they're fairly questionable it's still worth a deeper look.
Naturally, the first place I went was Wikipedia. However, her name isn't on that chart. I wonder, however, if her name would be just outside that chart. She's referred to as a "princess" but that could mean anything, really. But we all know how wide an actual family tree can be, so it's entirely possible that her name is somewhere adjacent to that direct lineage.
Are there any resources I might be able to check for something like this? I haven't done a lot of direct research myself, so at the moment I'm just Googling around for sources. The current royal family has their own website, of course. And there are other websites dedicated to the same family. But so far I haven't found anything better than that Wikipedia page.
Note also that her birth would have been pretty close to the space between the first two trees on the Wikipedia page, somewhere around Frederick I or Christian III. So if there was some sort of changing of the houses around that time then a lot of people may have called themselves a "princess."
Might there be more expanded lineages that I can dig up somewhere?
Edit: The actual person in question is listed in my sources as "Princess Biurnag (Bernice) of Denmark" (DOB unknown) who was married to Aongha Mhartain of Skye, Scotland (born 1558). They had a son in Skye, Scotland named Taos Gille Mhartain. (I've sent an email to the address named in the linked source.)
