Most Sea Wolf names look like someone mashed their face into a keyboard anyway, so I'm sure you're fine. 
And if anyone gets nitpicky, you could always blame it on a regional dialect or a simplification of the name to be easier on non-Roegadyn tongues. I just like playing with the names, myself - the naming conventions really interest me.
That said, I could try to make something close to Honest Leaf (which by itself would be a valid Hellguard name, by the way!) using the dictionary as given if you'd like. Just a quick scan gives me Rheti (Straight/Lawful) and either Brym (Tree) or Blyss (Blossom). So that'd be Rhetibrym (Lawful Tree) or Rhetiblyss (Lawful Blossom). You could also use Loetr (Pure) instead of Rheti for Loetribrym and Loetriblyss, respectively.
The last name is also perfectly fine, though there is potential to be had there as well. The Naming Conventions post I linked mentions that Sea Wolf surnames are often Son (-syn)/Daughter (-wyn) of [Father's Name]. So if he was named, I dunno, Fraefolg (Free Bird!)... then it'd be Fraefolgwyn for her surname.
That said, there's nothing saying you have to do that. Perhaps she is distancing herself from her father in some way or form, and uses that surname instead. Or maybe she doesn't even know her real father. Or she just wants people to know she's a good woman. It doesn't even have to be her real name - it's not uncommon for people to use aliases. There's a lot of potential information and ideas that can be pulled from just a name, which is why I think fantasy naming conventions interest me so much.
