The answer is: Keturah

Gen 25:1

In the biblical narrative of Genesis, we get a special glimpse into Abraham’s later life and family complexities through the mention of Keturah. After the passing of Sarah, Abraham marries Keturah, and she bears him six children: Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah. This connection furthers the story of not just the lineage of Isaac, but also the variety in Abraham's legacy through these descendants.

Keturah’s name means "incense," which could symbolize the fragrant and poetic aspects of her role as Abraham's wife, bringing richness and complexity to his story. Fun fact: Recognizing the importance of genealogy in the Hebrew culture, the descendants of Keturah would go on to play vital roles in the history and development of cultures surrounding Israel. The Midianites, for instance, descended from the Midianites would feature prominently when Moses fled Egypt.

Interestingly, although Keturah is often overshadowed by Sarah, the cultural context illustrates humanity's deeply rooted connections through kinship—wealth, history, and social standing were significantly tied with family lineages. Keturah, in her own right, is part of the broader gentile narrative echoed significantly throughout the scriptures, showing that the covenant’s blessings extended far beyond Abraham’s immediate family line through Isaac and Jacob. Life’s canyon of complications brings divine grace at every corner, making the story a powerful reminder of inclusivity in purpose and promise.
