Do you have any example of what typical troll names sound like?
Also, I think you mentioned that trollkin don't have genders in the way other races do, did I get that right?

Trollish language is based on Welsh, so named Trollkin I've used in things so far include Daffyd, Bryn, Angharad...

And yes, that's right. Orcs and Goblins can't reproduce, they're birthed by Trolls, so for all intents and purposes they're agender or you might think of Orc or Goblin as being gender roles in their society; Orcs are strong, Orcs build, Orcs are stoic and rational whereas Goblins tinker, Goblins explore, Goblins are impulsive and emotional. Sometimes Trollkin will refer to members of other species as Orcs or Goblins based on these stereotypes where we might say woman or man.
Trolls, as the reproductive members of the species who don't require fertilization to conceive the other two, and as a society who worship a mother deity, tend to default to feminine pronouns and signifiers among outsiders. Think of it as a kind of parthenogenesis. 
Trolls do need sexual intercourse to conceive more Trolls, so among themselves the gender divide is more 'one who has birthed a Troll', 'one who has not yet birthed a Troll', and 'one who conceived a Troll'. There is a powerful stigma around infertility among Trolls, so pernicious that a Troll who can't reproduce is declared Untroll. 
Biologically, you might say Trolls are male until around their thirties and then they transition to female for the remainder of their lives.
As you might imagine, they have largely given up trying to explain any of this to foreigners.

I will also not blame you for not wanting to engage with all of that and going with something more familiar, since any Troll pirate is likely an exile and has probably adopted the norms of their new home.
