Now, I pronounce "era" like EER-a (or, in other words, like the word "ear" with an A on the end). However I don't think that's what you have in mind, because with my pronunciation Linnéa would be lee-NEER-a. But from your discription, Linnéa should be closer to lee-NEH-a, right?
This is the trouble with translating pronunciations, isn't it? It's hard to write out the pronunciation. I have tried looking for sites with Swedish name pronunciation soundbytes, but I came up empty.
