In 2014 Maha Farid Mostafa published an inscription, found in the tomb of Shemay. The inscription belongs most likely to Idy, a son of Shemay, albeit Idy's name is not preserved. The text is dated under a king with the name Pepy and with a throne name Nefer-ka -Ra. Maha Farid Mostafa reconstructed that throne name to Neferirkare. The inscription dates for sure to the 8th Dynasty. If this reconstruction is correct, Neferirkare is most likely identical with "Demedjibtawy". Idy is mentioned on one of the Coptos decrees together with "Demedjibtawy" .
