Wizard Grandparents & long life?

Hi All!

I have a question here that I've been wanting to ask (but then 
forgot), which someone just brought up in a recent post.

Okay, DD is 150 years old, which I interpreted as not being uncommon. 
Why have we not heard about other older people - like great-grandma 
Weasley? 

My thought has been that they were all killed during Voldemort's 
first rise to power. You know, the "I've lived my life, so let me 
sacrifice so you can live" speech. Maybe they were all killed earlier 
by Grindelwald in 1945 (remember DD's chocolate frog card?). You 
would think otherwise there would be a huge amount of older wizarding 
people.

What about Mudbloods/halfbloods? Do they live long too, or is it cut 
shorter because of parentage?

Someone did mention to me that since the world is viewed through 
Harry, there are probably some, but he just never mentions it. 
However, again, you would think Ron would say something about great-
grandma Weasley and either that she's dead, alive, or estranged from 
the family.

Anyway, just a few thoughts. Wanted to hear what you all think. I'm 
sorry if this has been discussed at length before, which I'm sure it 
has, but I haven't seen anything about it within the year.
