Sturgis Podmore related?

No: HPFGUIDX 68716

I realized something that i had never notived before until the fifth 
book: 

The ghost who is the Leader of the Headless Hunt, Sir Patrick 
Delaney- Podmore, from CoS, has the same last name as 
Sturgis Podmore (part of the OOTP)

Are they related? 

If they are, I'm pretty sure this relation is not vital or essential to 
the plotline, or it might actually come to be something interesting 
later in the books. 

What to you think?
