Of unknown origin, the name of Herneith is associated several times with that of Horus Djer, suggesting that she may have been one of his queens.
Her name is found in a Saqqara tomb (S3507) assumed to be hers, as well as at Umm el-Qa’ab. Some of the signs accompanying her name have been interpreted as titles confirming that she was indeed a queen. There are no sources that would indicate that she was the mother of Djer’s successor, Djet.
Mastaba S3507 at Saqqara was found to hold several objects bearing the name Herneith, and is believed to have been her tomb.
