I'm not George, but I would say that you could use Anastasia, or just Stasia. As far as actually looking up equivalent meaning, I haven't done that. This is just a phonetic\homophonic equivalent.
As far as the date...assuming output from Diurna is correct (Diurna is a program I wrote a few years back that I have not tested as much as I would like yet)
AD\CE form: a.d. IV Id. Mai. MMIX
