Isola delle Femmine (Sicilian: Isula dî Fìmmini) is an Italian town in northwestern Sicily, administratively part of the Metropolitan City of Palermo.

[3][4] There are no reports of artifacts of a prison on the island, in spite of the fact that cisterns dating to the Carthaginian period, 100–200 years before Pliny's letter, have been found and still exist along with supporting documentation.

[3] The cisterns were used to ferment mixtures of fish scraps, spices, and oils into a sauce called garum, which was highly-prized in the Roman era.

[6][9][10][11] It does seem clear that the people of the area remember parts of this legend, as evidenced by "Lungomare Eufemio" street and a Hotel Eufemia are located in Isola delle Femmine.

Another possible origin of the name starts with the fact that a structure called a tonnara (derived from the Italian "tonno", meaning "tuna") was built, connecting Isola delle Femmine to the small island across from it.

[14][15] Translated into English, it reads: "... with all the responsibilities and appurtenances, to the monastery is granted and donated the tonnara which is on the island called Fimi, near the Port of Galus...".

With this decree, William gave Theobaldus, Bishop of Monreale (who had built a monastery there in 1174), this tonnara and it referred to the island by the name "Fimi".

The court language was thought to be Norman-French but official documents, especially those dealing with the Church were written in Latin as demonstrated by the decree of 1176 discussed above.

[3] Due mostly to economic conditions in the late 19th and early 20th centuries, large numbers of Italians emigrated from Italy, many to the United States and especially California.

Those from Isola delle Femmine found three California cities attractive due to the good prospects of commercial fishing there as well as the mild climate closely resembling that of their birthplace.

The parents of famed baseball players Vince, Joe and Dom DiMaggio were born and raised in Isola delle Femmine.

In 1992, through the efforts of a few Pittsburg descendants of immigrants from Isola delle Femmine, (including John Buffo) sister-city connection was established between these two cities.

Encouraged by these efforts, an organization named Friends of Isola delle Femmine was formed with the purpose to further cultural and educational exchange between the two cities and to promote understanding by future generations of their ancestry.
