Royalty in WW after all?

No: HPFGUIDX 105618

Ok, I have way to much time on my hands here  I was just looking 
through something when I came across this. Not sure what it could 
mean, if anything: 

Andromeda was the princess of Ethiopia, daughter of Cepheus and 
Cassiopeia. 

That would give us our royalty aspect of HBP. I was looking up 
Andromeda on the Lexicon but there is virtualy nothing on her. All 
we know is that she married Ted Tonks (Whom we know NOTHING 
about)...do we know anything else? Does Tonks have a brother????
