List of all childrens children

Questions
1

Hi guys!

Right now I print a list of the first year’s children seeing as thats how far I’ve come.

The Content structure looks like this:

Articles

2013

Article 1

Article 2

2014

Article 1

Article 2

And the code I have so far looks like this:

var root = Model.AncestorOrSelf(1).Down(1);
var selection = root.Children.OrderBy("homepageArticleDate desc");
@foreach (var item in selection) 
{
    here I do stuff..
}

Now what I need to do is run through all of the years (I have from 2002-2014) and show their children (a hard way to say every single article ever written).

And can I then still sort them from their descending date?

Every help I can get would help, thank you !
