During the 18th dynasty he appears on several monuments. Such prominence is relatively rare in case of princes who never ascended to the throne, so it has been suggested that he might be identical with the unknown father of Thutmose I, who succeeded Sipair's nephew, the childless Amenhotep I. However, the mummy identified as his is that of a 5- to 6-year-old boy. The mummy was found in the Deir el-Bahri cache in 1881 and was unwrapped by Grafton Elliot Smith and A. R. Ferguson on September 9, 1905.
The location of his tomb is unknown, however it was still known during the inspection of Tombs in the 20th Dynasty mentioned on the Papyrus Abbot.
