St. Phoebe the Deaconess. In the early Chuch there were women deacons. However, they were limited to that role and were not allowed in the priesthood. The reason for the deaconesses: it was considered improper for males to be physically handling women, so deaconesses were commissioned to assist especially in baptism and chrismation. While there are no liturgically recognized female deacons in the Orthodox Church in the USA, there are some in Japan, Russia and Greece.
St Tatiana was a Christian martyr in 3rd-cen. She was a deaconess of the early church. Ulpian captured Tatiana and attempted to force her to make a sacrifice to Apollo. She prayed & miraculously, an earthquake destroyed the Apollo statue and part of the temple. Tatiana was then blinded & beaten for two days, before being brought thrown into the pit with a hungry lion. But the lion did not touch her & was later beheaded with a sword
