I'm not sure how coherent i can be on this but I'll try. (Aside: If all you know Nabokov for is Lolita then you are missing one of the funniest serious writers of the 20th century.)
OK, basic similarities are on the surface, Ada and LB are family sagas of complex patterns, covering what may be generations. Where LB interacts with Faerie, to the extent that Faerie-world and LB-World are contiguous, then similarly Ada seems to occupy a parallel earth contiguous with our own, and the family in the novel pass between the two as they move from family into world-at-large and back again.
