While I would love to chime in IN CHARACTER, with Dilly Nackle that is not really an option as most of her character flavor comes from the speed and tone of voice and I have yet to find a way to convey that via type. SO OOC it is.
Nackles like us are a group full of flavor and fun, none are exceptional power characters or min/max broken characters. We will speed precious skill points in crafting/profession categories because it fits with the flavor of a character (ie brewing and such) while this may help for a day job roll, not much good anywhere else.
That said there are a few FAUX NACKLES out there, if you have ever left a table with the thought of never playing with that "player" again or would like to see that "player" drop kicked into orbit they were probably a faux Nackle, we had a rash of them pop up before the end of LG and they used the Nackle idea to be complete a$$hats.
True Nackles while we can get annoying in large groups are a great bunch of players who know where the line is and will play near it but don't cross it (let's face we are circus folk). While the characters generally have marginal stats, we are usually creative thinkers with the experience to make up the difference. That is part of why we generally need a token tallie with 5 Nackles (Somebody has to be able to reach stuff).
As far as Golarion, we Oerth Nackles did track down a 1st cousin to Poppy Nackle and found he did have a traveling circus too - Cousin Hempy Schroom Nackle.
We have a chillin' classic garden gnome statue that we used for Poppy and took to conventions that we hosted/volunteered at, then we found one decked out in board shorts and Hawaiian shirt, with flowered hat and smoking a pipe and he became our Golarion gnome Cousin Hempy.
Happy playing and if you play a Nackle - do the family proud and shut down a table with laughter once in a while. Our current record is 5 tables at once with a complete stop in play for laughter at a convention.
