Thanks for the early entries - much appreciated. In #1 we like that both N and K are represented in the icon - this is preferred to just the K as in #2. For the wordmark - I think we need to look at two different fonts, or at least two different weights, to bring some separation to the firstname and lastname - especially as we have two "K's" next to each other.
Thanks for the new entry. We're not too keen on having two stylized K's, but would like to see a version of #1 with two different fonts or weights for the words "Nick" and "Kellet".
