There's two possible approaches to names: you could either look up the meaning of Valerie (looked it up, it means brave/fierce) and find a similar word in Dovahzul (kril/norok, literally), or, like you suggested, just use Valerie. Although the -ie ending is atypical, the name in a Dovahzul sentence would by most people be recognized as a name.

The year is something that is both harder and easier. Harder, because our number system isn't canon (it has been made up by the community, and does not appear in The Elder Scrolls. This is something you might dislike, since it is not official), yet easier, because the number system does have set rules, which can be found here. As an alternative you could consider using Roman numbers for the years.

Personally, I would go for just using the English name written in runes, and the year in Roman numbers. It's all up to you though!
