You have a European Y-chromosome. I recognized R1b as a European haplogroup and did a google search for it with the marker M343. Your brother should have received the explanatory material this person has posted.

It includes a map showing how the DNA started out in Africa, and over thousands of years mutated again and again into different groups along the way. The various mutations are assigned names and the one that identifies your population group is M343. You can see on the map where the various groups are now located in Europe.
