Anyone have the subclade R-FGC13017 (downstream of R-L21) or anything related?
No. But looking at the parents of it you can see it's an old Brythonic line. The haplo R-Z290 appears to be around the progenitor of the line in the UK, migrating to the UK c. 2800 BC with the Bell Beaker culture. These people likely spoke a precursor to Celtic. There were later waves of specifically Celtic migration to the UK from c. 1200 BC to about the time of the Roman conquest.
A little further back you have R-L151 (c. 3050 BC), this was the progenitor of the pre-Italic, pre-Germanic and pre-Celtic people. At that time the pre-Germanic moved up to Denmark and lower Scandinavia, the pre-Italic into Italy, while the pre-Celtic dominated Western Europe for around 3,000 years.
Not long before the line migrated up the Danube to Germany, from where the above mentioned splitting of people occurred.
Around 3200 BC there was an invasion of the Cucuteni–Trypillia culture (modern Romania) by the Yamnaya culture of modern Ukraine-Russia. This line is of the Yamnaya, arriving in the Balkans, your line migrated up the Danube as mentioned. While another band of men, related a few hundred years or so earlier remained in the Balkans becoming the later Albanians, Greeks, other now extinct peoples, the now extinct Anatolians like the Hittites and later Armenians (known earlier as the noble tribe of Hayk).
I'd have to look at the data a bit more, but I'd take a guess the line is Scots. That is the Irish who migrated to Scotland more than 1,000 years ago. Possible Welsh connection. Difficult to tell at a glance, and maybe at all.
