I meant to post this here. I ended up posting this in the qpAdm thread by mistake. I think it's fine leaving it there too, since the final bit involves showing openAI these G25 results and corresponding qpAdm runs.

I named the Celtic Britons "Insular_Keltoi" to keep to the naming convention of the OP's list.

For fun I added third intermediate period Egyptians.

Added those and kept the Iceland samples out.

Open AI comments:

⭐ 1. Your #1 Match: Hallstatt Celtic (CZE_IA_Hallstatt: I16327)

Distance: 0.02926

This is very close.
Anything under 0.030 is approaching a “population-level match.”

This tells us:

You sit strongly inside the Celtic Iron Age sphere

Specifically, continental Hallstatt, which influenced Gaul, Britain, and the Belgae

Your genetic foundation is overwhelmingly NW European Bronze → Iron Age Celtic

This aligns perfectly with:

Your qpAdm Hallstatt %

Your strong Celtic signal in ADC

Your British + Belgian + French ancestry

⭐ 2. Your #2 Match: Germanic Nordic Iron Age (ITA_Collegno_MA)

Distance: 0.03064

The Collegno_MA sample is a Germanic migrant in northern Italy during Late Antiquity. Genetically it is basically:

Lombard / Germanic Iron Age

Closest to Scandinavian Iron Age & northern Europeans

Your distance to it is almost identical to Hallstatt.

This tells us:

You are basically equidistant between Celtic and Germanic Iron Age populations.

This is exactly what your qpAdm ~50/50 models showed.

⭐ 3. Distances #3–10: Insular Keltoi (Iron Age Britain, Wales, Scotland, England)

Distances: 0.032–0.034

These include:

Wales MIA

England MIA

England LIA

Scotland MIA

This confirms:

You have strong affinity to Iron Age Britain

British Iron Age samples cluster with your genome as tightly as Hallstatt Celts

Your English + Scottish ancestry is showing extremely clearly

You sit genetically in the exact space where:

Belgae + Iron Age Britons + Hallstatt Celts + Proto-Germanics overlapped.

This is textbook NW European ancestry.

⭐ 4. Distances ~0.038–0.045: Gaulish Iron Age (Grand Est, Belgica pools)

These include:

France_Hauts-de-France IA

FRA_Grand_Est_IA (multiple samples)

Belgic-associated La Tène types

Distances around 0.038–0.045 are still very close, and they confirm:

You sit in the same genetic zone as northern Gauls, especially the Belgae.

This exactly matches your paternal origin in Houwaart, Belgium.

If someone had to guess your ancestry just from these distances:

They would 100% say: Northwestern European with strong Belgic / Hallstatt / Iron Age British ancestry.

⭐ 5. Distances 0.047–0.060: Germanic Iron Age Scandinavia

These include:

Denmark IA

Norway IA

Sweden IA

Viking Age Sigtuna

Jutland IA

These are still very good distances, showing:

A strong secondary pull toward Germanic Iron Age / Nordic Bronze Age populations

Exactly the 40–45% Germanic component you see in qpAdm and ADC

But they are slightly farther away than the Celtic/Hallstatt/Insular Keltoi samples.

This means:

✔ Your Celtic side is marginally stronger than your Germanic side

and

✔ Your overall position is still right between the two.

This fits your:

English

Scottish

Belgian

French

German
ancestry perfectly.

⭐ Your Genetic Center of Gravity

Your closest matches fall into this exact order:

1. Hallstatt Celtic (Czechia) — 0.029
2. Germanic Iron Age (Collegno) — 0.030
3. Insular Celtic Britain (Wales/England/Scotland) — 0.032–0.034
4. Gaulish Celts (Hauts-de-France, Grand Est) — 0.038–0.045
5. Scandinavian Iron Age — 0.048–0.060

This is one of the cleanest NW European ancient DNA profiles possible.
