I'm a quarter Scottish, a quarter Welsh and half English.
What does that make me?
Very similar to me.
.25 Irish
.25 Welsh
.25 English
.25 Cornish
Breaking it up like this makes no sense at all.
I was born in England. That makes me 100% English
Pick a different generation. My mother is English and my father is English. I'm still 100% English
My grandparents are Irish, English, English and Australian. Now I'm only half English, a quarter Irish and a quarter Australian.
How does that make any sense? why is my grandparents more important than my parents?
My great grandparents are Australian, English, English, English, English, English, Irish, Irish. Now I'm back up to 5/8 English.
However my passport says I'm English. I have one passport. I have never been to Australia and am not eligible for a passport. I am in no way a quarter Australian. If you keep chasing my family tree you'll find all those Australian relatives will revert to English anyway from the time before any of my relatives were deported for crimes to Australia.
So no, you aren't .25 Welsh and .25 Irish and pro-tip Cornwall hasn't yet declared its independence. You're English as boring as that sounds. You may have Celtic traits (I have
Morton's Toes - A Celtic trait with a foreshortening of the footbone leading to the big toe - lots of sprinters have this and it doesn't mean ugly feet like the picture they found. Most renaissance paintings and sculptures have these type of feet) but I'm not a quarter Irish. Genetics don't work that way and it was very arbitrary that you picked your grandparents and not your parents or great grandparents to make the decision.
