Origin
The surname "APAP" has its origins in the Mediterranean region, specifically in the areas around modern-day Greece and Turkey. It is believed to have derived from the Greek word "apalos," which means "soft" or "tender." This suggests that the name may have initially been used as a descriptive term for individuals with a gentle or mild demeanor.
One of the earliest records of the name "APAP" can be found in Byzantine manuscripts dating back to the 12th century. These documents mention individuals with variations of the name, such as "Apalos" and "Apalides," indicating that the surname had already been established by that time.
During the Ottoman Empire's reign, the name appears to have spread to other regions of the Mediterranean, including parts of modern-day Turkey and the Balkans. In the 16th century, there are records of an Ottoman official named Ibrahim Apap, who served as a governor in the region of Morea (present-day Peloponnese, Greece).
In the 18th century, the name "APAP" began to appear in historical records from the Greek islands, particularly in the Cyclades archipelago. One notable figure from this period was Georgios Apap (1720-1794), a merchant and ship owner from the island of Syros, who played a significant role in the island's economic development.
As the Greek diaspora spread across the Mediterranean and beyond, the name "APAP" traveled with them. In the 19th century, there are records of individuals with this surname living in various parts of the Ottoman Empire, as well as in Italy and other European countries.
Another notable figure was Alexandros Apap (1845-1915), a Greek linguist and scholar born in Izmir (then known as Smyrna), who made significant contributions to the study of the Greek language and its dialects.
Throughout its history, the surname "APAP" has also been associated with various place names and older spellings. For instance, the island of Lipsi in the Dodecanese archipelago was once known as "Apapli" or "Apapalia," which may have been derived from the surname.
Other individuals of note who bore the surname "APAP" include:
1. Dimitrios Apap (1835-1905), a Greek soldier and military leader from Crete.
2. Konstantinos Apap (1865-1932), a Greek painter and art educator from Syros.
3. Eleni Apap (1879-1961), a Greek writer and feminist activist from Syros.
4. Aristidis Apap (1890-1953), a Greek politician and diplomat from Thessaloniki.
5. Ioannis Apap (1920-2002), a Greek theologian and academic from Athens.
Demographics
Among Census respondents with the surname Apap, the largest self-reported group is White at 93.1%. The next largest groups are Hispanic (3.4%) and Black (1.7%).
The bar chart below shows how Apap bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Apap surname at the time of the 2020 Census, not any inherent property of the name itself.
