One of the earliest known references to the Aunspaugh name can be found in the records of the city of Nuremberg, where a certain Hans Aunspaugh was listed as a resident in the year 1572. Another early mention of the name appears in the parish registers of the town of Schwäbisch Hall, where the birth of a child named Anna Aunspaugh was recorded in 1598.

Another prominent figure was Katharina Aunspaugh (1712-1789), a renowned midwife in the small town of Büdingen. Her expertise in childbirth and her compassionate care for mothers and infants earned her a reputation that extended far beyond the local region.

One notable American bearing this surname was Samuel Aunspaugh (1834-1911), a Civil War veteran who fought for the Union Army and later became a respected community leader in his hometown of Allentown, Pennsylvania.
Another American of note was Anna Aunspaugh (1880-1962), a prolific writer and poet from Ohio. Her works often explored themes of nature, spirituality, and the human experience, and she was widely published in literary journals and anthologies during her lifetime.
