Remember that girl you got to join the Dawnguard? You can buy them from her in Fort Dawnguard.
I'm not there yet, I guess... Currently, I am trying to recruit this lady into Dawngaurd but she wants Gyros of some sort so she'll tag along, this might be the same person you're speaking of.
That is the same person. She functions as a vendor later, she sells a -blam!- ton of elven arrows and crossbow bolts. She also has a quest that'll teach you how to make Dwarven Crossbows.
