Odd GEDMatch results for my British grandma.

[Bunalim]

Consistently getting 15~25% non-British results on Oracles. Her family tree shows nothing but Irish, English and Welsh for as far back as the tree goes (400~500 years on each branch). Her father though (my great-grandfather), in my opinion looks quite swarthy so I'll include some pictures of him. If anyone has any ideas, please let me know :)

I'd recommend taking a look at the Gedmatch spreedsheet (it's another button, near the oracle buttons) and seeing how her individual components stack up to the averages from Irish, English populations etc. Perhaps she has just a bit more Med than average? Her father looks Med influenced to me.

Is she from SE England?

My grandmother was born in New Zealand but I'll tell you where her grandparents are from.

Grandfather #1 is 3/4 Welsh, 1/4 Irish
Grandmother #1 born in Wales, has a typical Welsh name
Grandfather #2 is English, from Yorkshire
Grandmother #2 is English, from Wiltshire

Lower Baltic and higher West Med. I guess she's more Mediterranean than average.

Are the results that strange? I'm not seeing it.
