I also really enjoyed the gnomes until Generations. Then all the gnomes not only aged and died, but appeared in all my lots and all my different worlds. Wowww. I was deleting 'nome headstones' for a couple weeks. I think they are all gone now. Haven't seen one for a while. I just delete any regular gnomes now.
There are quite a few specialty ones. I have several. From WA, and some of the professions and products made by the sims. I don't want to give it all away. They are fun, don't age and come as a complete surprise. I won't be deleting these ones. I really enjoy them. I look forward to getting more.
