If you're asking what % of the modern Irish population is of English descent, Danish descent, and so forth, here's a good place to start: http://www.eupedia.com/forum/showthread.php?24907-Genetics-of-the-British-and-Irish-people
But since much of the information is of a technical sort, (requiring a fair grounding in the language of human genetics), it'd take quite a bit of study and a fair amount of number crunching to nail down percentages across various lineages.
An estimate is however given which states that roughly one quarter of today's Irish population descends from English stock (paternally). We'll understand how necessarily 'approximate' this has to be because, of course, what it means to be English is itself up for grabs as, yes, they too are an amalgam of peoples in their own right.
Based on the presence or absence of specific genetic markers, (and groups of markers, really), great gains are apparently being made toward clearing all of this up though. So the day may soon come that such questions can be answered with greater ease and confidence.
