Are there surnames that are more prominent from one island to another
island?

[Cheri Mello]

Yes there are a few that cluster more than others. Bettencourt is found more often in the central island group, for example. As for Silva, it's all over the place.

Several years ago I read a scientific study that was posted online
seeking to determine whether any surnames in the Azores were
characteristic of a particular island. The only one with statistical
significance was the surname JORGE on PICO. Unfortunately, a cursory
web search tonight isn't bringing up the article. Does anyone else
recall it, who can help locate it? (It might've been in Portuguese,
but I can't recall for certain any more). Katharine.

Abstract
Geographic isolation is a significant factor to consider when characterizing human populations. The knowledge of the genetic structure of isolated populations has been of great importance to disease-locus positioning and gene identification. To investigate the genetic structure of the Azorean population, we conducted a survey based on the frequencies of surnames listed in the 2001 telephone book. We calculated the following parameters: isonymy (I), the random component of inbreeding (F_ST), genetic diversity according to Fisher (α), Karlin-McGregor's migration rate (ν), and Nei's distance. For the 1,271 subscribers and 163 different surnames, Graciosa island presented the lowest value of abundance of surnames (α = 15.75), suggesting great genetic isolation compared to the other eight islands. Migration, calculated on the basis of the diversity of surnames within islands, ranged from 0.2747 (Corvo island) to 0.0026 (São Miguel island), indicating that people migrated preferentially toward the economically more developed islands. The value of the random component of inbreeding obtained for the whole population (F_ST = 0.0039) indicates little genetic differentiation (Wright's F_ST<0.05). Moreover, isonymy similarity revealed using the UPGMA method shows three subclusters corresponding to the geographic distribution of the islands.

Medeiros in Sao Miguel, Faial and Pico, Quadrado in São Jorge, Pimentel in Sao Miguel, Rebolo in Terceira. JORGE was originally patronymic, and it'll be very common, but its branches are not necessarily relatives.
