Yes, Mare is the boy, the younger brother to Aura, the older sister. This was done by Bukubukuchagama (Shimmering Teapot in Skythewood's translation).

Even right at the start in both the book, manga and anime, pay attention to Demiurge and Mare's first conversation with each other (while Albedo and Shalltear cat fight in the background). Demiurge says to Aura that he's going to the leave such matter's to Aura as it should be dealt with by the girls (much to Aura's complaint). The guys then walk a bit away and talk about a possible Heir from Momonga. Cocytus fantasizes being called Uncle/Sensei while Mare gets confused (possibly doens't know where babies come from.  Demiurge then asks Mare why he's dressed like a girl and Mare replies that he's certain he's a girl, but that Bukubukuchagama (his creator) said that he was an "Otoko no Ko", which essentially means a trap in the loosest of terms.  It's just part of Bukubukuchagama's tastes having the two cross dress.  As well as Mare's submissive attitude toward Aura may be because Bukubukuchagama believe that a younger brother should be submissive and listen to the older sister (a quip toward Shalltear's creator, Peroroncino, who is her actual younger brother).
