In the recent HBO Harry Potter trailer, we got to see something we've never seen before.

Our first glimpse at Harry's grandparents on his mother's side.

They appear standing alongside Vernon and Petunia Dersley in their wedding photo,

with presumably Vernon's parents on one side, and Petunia's parents, aka Lily's parents, on the other. And with this new bit of info,

it got me thinking, what did happen to the rest of Harry's family? Cousins, uncles, aunts,

grandparents that we see in the trailer, Lily and Petunia's parents, the Evans. The law

states that both of Lily's parents died normal muggle deaths without going into any detail.

We know that they both died sometime between 1971 and 1981, because in

1971, they saw Lily off to Hogwarts at Platform 9 and 3 quarters, and in 1981, Lily

was murdered. We know them to be dead at this point. It's unusual that they would have died

in this time frame, and I'm really not sure what constitutes a normal muggle death.

It definitely isn't old age because they would have been far too young. After all, Lily and

James are only 21 themselves when they died. So even if they had Lily quite late, a fair

assumption is that they couldn't have been that old. So if it wasn't old age, what's a normal

death? Cancer, heart attack, it's really

hard to say. Provided that all of the information we have on their deaths, groups them together,

and that they were so young, I strongly suspect some foul play. Lily and James were both very

outgoing witches and wizards, joining the Order of the Phoenix and actively participating in the
