This is quite useful as a reference for those interested in E-M35 and its many subclades.
A quick comment on p. 53 where Sicily is discussed and the prevalence of R1b and I1 in the West is mentioned in the context of Phoenicians who settled in West Sicily.
Haplogroup I1 is probably to a large degree due to the Normans whose capital was in Palermo (NW Sicily). R1b on the other hand may have been added by the Normans, but may also be due to the pre-Greek populations of Sicily, such as the Sicani who were (after Herodotus) of Iberian origin.

Y Haplogroups, Archaeological Cultures and Language Families: A Review of the Possibility of Multidisciplinary Comparisons Using the Case of Haplogroup E-M35
Archaeology, comparative linguistics and population genetics all have something to add to speculation about early human migrations, and the three disciplines often make reference to each other in broad terms. But, in reality, the results are often disappointingly indecisive. This article explores the case of Y haplogroup E-M35 (E1b1b1), which has so far mainly only been mentioned in a passing way in archaeological and linguistic debate, but which, it shall be shown, shows great promise as more detailed about it's phylogenetic structure, and its regional distribution becomes available each year.
