Hello, it is interesting to see the L241 there. About it's origins, well there are several affinities L241 seems to have, NW Balkans, NE Balkans, and for some it is Greece. Additionally L241 is found from the East to the West fof Europe.. Unfortunately not too many Greeks have been tested for deeper clades (well none of L241's), and closest to you is an L241 Greek from Messinia, 5/37, you also share with him somewhat unusual values for L241 on CDY, 34-36 and 33-36, that also points to me that you are likely related. Would you consider doing some SNP tests under L241, because I couldn't really classify this Greek and fit him into existing branches well, I suspect you might form a new L241 branch with him. I think they have all main branches at both ftdna and YSEQ.
Of course Greek activities were attested in North Africa so it would make sense. Connection with Dorians is a very real possibility for Greek L241 branches.
Your have some off-modal values like dys391=9 and dys385b=16 which might indicate greater distance than would 5/37 match suggest, it is difficult with 37 STR's to judge the distance for L241.
In addition to this L241+ Greek there is another Greek from Peloponnese which looks like L241 and also one from Euboea. Also there is one from Cyprus and great many Cypriot haplotypes from scientific studies are certainly connected to him. I think I managed to identify his likely branch under L241, however him and these other likely L241's are not so close to you.
