The name Keturah has its origins in the Hebrew language and culture. It is derived from the Hebrew word "qeturah," which means "incense" or "fragrance." The name first appears in the Old Testament of the Bible, where Keturah is mentioned as one of the wives of the patriarch Abraham.

According to the Book of Genesis, Abraham took Keturah as his wife after the death of his first wife, Sarah. Keturah bore him six sons: Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah. These sons are believed to have become the progenitors of various Arabian tribes and nations.

The name Keturah holds significant meaning in the Judeo-Christian tradition, often symbolizing fertility, abundance, and the continuation of Abraham's lineage. In some interpretations, Keturah is seen as a representation of Abraham's spiritual journey, as he moved from the familiar to the unknown, embracing new experiences and blessings.

One of the earliest recorded examples of the name Keturah can be found in the biblical account itself, dating back to around the 2nd millennium BCE. Throughout history, there have been several notable individuals who bore this name.

Keturah Whitford (1832-1921) was an American missionary and educator who established schools in Persia (modern-day Iran) and worked tirelessly to promote education and women's rights in the region. Keturah Stickney (1824-1890) was an American author and abolitionist who wrote extensively about the struggles of women and the abolition of slavery.

Keturah Bingham (1789-1847) was an American pioneer and early settler in Ohio, known for her bravery and resilience in the face of adversity. Keturah Chandler (1832-1892) was an American educator and women's rights activist who fought for equal educational opportunities for women in the 19th century.

Keturah Leitch (1849-1925) was a Scottish missionary and teacher who dedicated her life to educational and missionary work in India, establishing several schools and orphanages for girls in the subcontinent.

While the name Keturah is not as widely used today as it once was, it still holds a rich historical and cultural significance, particularly in the Judeo-Christian tradition and among those with an appreciation for its biblical and linguistic origins.
