98% ethnicity given

[LadyEloise1]

Someone has matched with DH and they are showing 98% ethnicity estimate as Irish.
No other estimated ethnicity given. But they are missing 2% ethnicity.
We've never seen this with a match before.
Seems odd that this person has only been given a 98% ethnicity estimate.
Every other person's ethnicity estimate has added up to 100%.

Don't these things work by matching where people who have given samples have come from?
So if the 2% is something obscure like, I don't know, Hawaii, then it won't be matched against.

Ah ! Thanks for replying.

I was going to say this, I’m an uncommon ethnicity in the west, so we don’t really exist on the data bases for these sites. I did one and it showed me as 8% white British, 42% Pakistani and that was it, the missing percent will be Balti.

Is this on Ancestry?
Frequently asked questions: Why don’t some people’s ethnicities add up to 100%?
AncestryDNA members choose whether to show all their ethnicities to DNA matches or to show only the ethnicities they have in common. If your match’s ethnicities don’t appear to add up to 100%, it’s because you’re only seeing some of them—the regions you have in common.

Yes it's on Ancestry.
It hasn't happened before with other matches hence dh wondering why, thank you @LozengeShaped

On Ancestry this person is being shown to be a first cousin of my dh. But he is the son of a first cousin of dh's mother so he can't be a first cousin of dh.
Why the discrepancy?
Confusing.
Any idea please ?

It is a suggested relationship based on shared DNA and probability. So you can see from the link that 2nd cousin overlaps with 1st cousin in shared DNA

Thank you @BramblyHedge

Had mine this week but 23andme. I have 0.1% unassigned which essentially means they don't recognise it as anything yet.

So the 0.1% could be an alien from space.

Of course! The only logical explanation.

Agree with this, I see this fairly often in my matches.
