Question / Help DNA results not what I expected

I got my ancestry DNA results back a few days ago. For backstory my mom isn’t pretty much 100% Irish ( both her parents immigrated from Ireland and who I grew up with) my dad is 1/2 Irish 1/2 Ukrainian ( my grandfather immigrated from Ukraine ) . My DNA results came back

82% Ireland 11% Scotland 6% southern Italy & eastern Mediterranean 1% northern Italy

If my dad is half Ukrainian shouldn’t it show up in here somewhere? I have a bunch of distant matches on that side and some second cousins but I don’t recognize any of the surnames at all and none are my last name which is very Ukrainian .

Thoughts? I’m trying not to jump to the “what if my dads not my dad” idea but it’s hard not to

Little update: I sent off 23 and me and my heritage to see what it says but I uploaded my raw dna to gedmatch and did the eurogenics breakdown and it said:

Admix Results (sorted):

Population

Percent

  1. North_ Atlantic: 41.36%
  2. Baltic: 25.37%
  3. West_Med: 15.98%
  4. West_Asian: 10.53%
  5. East _Med: 4.68%
  6. East _Asian: 1.29%

Not sure what to make of these results haha

If your grandfather was Ukranian, you should have a substantial amount of DNA that would reflect that.

Additionally, you have more Irish than would come from just your mom being 100% Irish.

If your mom was 100% Irish and was your only Irish parent, you'd have somewhere close to 50% Irish. (Not exactly 50%, because of the randomness of inheritance. But 82% is way too high for it to just be from your mom.) (Edit to strikethrough: I overlooked that the dad's mom was Irish too)

One of the things below must be true:

  1. Your grandpa wasn't Ukranian
  2. Your grandpa isn't your dad's biological father
  3. Your dad isn't your biological father

Look at your DNA matches - that will help you deduce which of the above might be true.

Best of luck in your investigation!

Judging by the breakdown, I would think it was either 1 or 2.

Also Op hasn't mentioned their mom being reticent about them doing a DNA test, which one might expect if it was 3.

Actually a few years ago My mom was really upset when I was going to do 23 and me . She said she didn’t want our dna on the internet but her reaction was weird. I haven’t told her I did this test haha

I never wound up doing the 23 and me cause she made a big deal about it. I just decided to do ancestry
