Okay...for instance


Here is the link to Wikipedia's "Black Family Tree";
Black Family Tree

Look at how many people in that family have constellations as names.


And then there is Tom Riddle.
His full name being <span style="color:#FF0000">"Tom Marvolo Riddle"</span>...is(as you should already know) an anagram of <span style="font-family:Arial Black">"I am Lord Voldemort"</span>

She does obviously put though into people's names.
