Kind of fitting that the sister was called Perpetua. In the catholic religion, the Perpetua is the woman (always have been, don't know if nowadays things have changed) who takes care of the priest of the parish. It was most often than not the priest's mother, but it also happened that the Perpetua was the sister. I don't know if Esdras was a prelate other than a soldier, but if that was the case, his sister being his Perpetua would be fitting.
