The maps show the distribution of our Y Chromosome J2. It spread from the middle east to Greece, the Balkans, Italy, France, and Spain. Our ancestor may have migrated from Greece, Italy, or the Balkans to Canton Aargau, Switzerland. J2 is associated with the spread of agriculture from the fertile crescent to Europe.
All three scenarios above are of course speculation and we cannot know for sure exactly how are ancestor reached Switzerland. DNA testing may eventually confirm this last theory, however. If a descendant of the Jewish Hollinger's from Romania or Poland test their "Y" Chromosome we can find out if we are closely related. If we are then this last path is likely. If not one of the other paths is most likely.
I have researched our name in Israel. There are a number of Hollinger's in Israel, who spell their name Holinger.
The table below is taken from the Wikapedia article. Our J2 numbers are at the bottom of the table. As you can see, our numbers are close to the Cohen J2 line. Mutations occur periodically, as shown in the table.
