So I just tested positive for R-BY3618 at YSEQ. I'll have to admit that I am not really sure what this means.

I noticed FTDNA has a map for R-BY3620 which seems to include people mentioned on Ytree listed as R-BY3618. Are they equivalent or related?

Is there anywhere I can learn more generally about my subclade, where it may have originated, how it may have arrived in the British Isles, or really anything more?

Based on some quick searching there isn't much in the way of information. There are too few samples to draw any definite conclusions, but I suppose the most striking observation based on those tested so far is with the exception of a kit with the surname Flori (which I presume to be either Italian or French) most samples are northern, or at least more northern than the U152 center of gravity. Most are English, one is Welsh, one Irish but with a possibly Anglo surname (Smith), and then there is a German from Westphalia and a Norwegian. Perhaps a Saxon connection? One can only speculate I suppose.

Generally, it is considered that the majority of U152>L2 in Britanic islands come with Belgians during the last centuries before JC.

Other posibilities : Romans (U152 is frequent in North and Central Italy > 40%, L2 is about the quarter ), Normans (U152>L2 in France and Belgium > 10%).
It exists but less frequent ( < 5%) in North Germany and Scandinavia.

In Britain, more frequent in East coast.

Yes this is indeed some of the general observations on U152 as a whole, but as noted while the sample size is currently quite small so far the majority of BY3620, BY3618, etc. is to be found in Britain, with the two primary exceptions being a man from old Saxon territory with a north German surname and a Norwegian.

Looking into the man I thought was French or Italian, it turns out the sample in question is Corsican but there is a study which seems to link this particular Corsican family with British Jacobites in 18th century Corsica.

In turn this means that at least so far none of the samples of my HG are in the traditionally U152 heavy spots on the continent, i.e. Eastern France, Northern Italy, Switzerland, SW Germany, etc. but rather has a more northern distribution. This northern distribution includes my own paternal line, either Scottish or Northern English origin. Here's the map with some of the samples I mentioned previously:

Hopefully more samples will come in or someone more expert than I can illuminate something further.
