In population genetics your X and Y is not a factor in your relationship to other populations. For example cousins can be a completely different ydna and not sure if by X you mean mtdna? But the same holds true. Ydna for example is good at looking at distant connections and the same with mtdna. Anyway both y and mtdna are not a factor in these lists as they are entirely based on autosomal dna and the same with plots showing which populations cluster with each other. So in the end y and mtdna are irrelevant in this.
FTDNA is the place for ydna and mtdna if you want to look into that further.
My brother's ydna uploaded to yfull. He is M222 so very Irish centric.
He's the one here marked in yellow. On FTDNA they go into a lot of detail and I know that ydna descends from the Northern Ui Neill. It is further down M222 (i.e. the so called Niall of the Nine Hostages marker).

I've also had the full mtdna sequencing done and that is also uploaded to yfull.
Mine is marked in yellow. Mtdna is more varied but all my full matches are Irish also.

This is from ftdna. I've got 3 exact matches in Ireland. The rest of the list is 1 step matches. As you can see mtdna is spread around more populations but relationships are more distant.

So while all is interesting to find out your closest relationships and relatives you need to use autosomal dna.
