Origin
Meaning and origin of Casab
The surname CASAB has its origins in the Middle Eastern region, specifically in modern-day Syria, dating back to the 13th century. The name is believed to have derived from the Arabic word "qasab," which means "reed" or "cane." This connection suggests that the earliest bearers of this surname may have been associated with the cultivation or trade of reeds or canes.
During the Mamluk Sultanate period (1250-1517), the CASAB name appears in several historical records, particularly in administrative documents related to land ownership and taxation. One of the earliest known references to the name can be found in a manuscript from the year 1287, which mentions a certain Yusuf al-Casab, a landowner in the region of Hama.
The CASAB surname has also been documented in various medieval manuscripts and chronicles, such as the "Kitab al-Nujum al-Zahirah" (Book of the Bright Stars), a 14th-century astronomical treatise written by Ibn al-Shatir. This work mentions a scholar named Ahmed al-Casab, who lived in Damascus during the late 13th century.
Notable individuals who bore the CASAB surname throughout history include:
1. Uthman al-Casab (1280-1345), a renowned Islamic scholar and poet from Aleppo, known for his contributions to the field of Arabic literature.
2. Zaynab al-Casab (1310-1378), a distinguished female physician and herbalist from Damascus, renowned for her expertise in traditional medicine.
3. Khalil al-Casab (1450-1520), a skilled calligrapher and illuminator of manuscripts, who worked in the court of the Mamluk sultans in Cairo.
4. Muhammad al-Casab (1580-1640), a prominent Sufi mystic and author from Hama, whose writings had a significant influence on Islamic spiritual traditions.
5. Fatima al-Casab (1670-1735), a renowned artist and ceramicist from Raqqa, whose intricate tile work adorned many mosques and palaces during the Ottoman period.
While the CASAB surname has its roots in the Middle East, it has also been documented in various historical records across the Mediterranean region, particularly in areas with strong trade and cultural ties to the Levant. However, the majority of references and notable individuals bearing this surname can be traced back to its origins in Syria during the medieval period.

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.
