Vivienne Evans. Too much???????

I think it sounds fine. A v-heavy name is a little different than other letters because the v sound is so crisp. If you were thinking Aurora Rollins or Eulalia Lane, I might think it was too much. Vivian Evans sounds nice!

I think it sounds great, and the Vivienne spelling looks fine to me. If you love it, go for it!

I think Vivienne Evans has a marvelous sound - very crisp and youthful. Generally I prefer the Vivian spelling, but I think the length of Vivienne balances Evans out well (maybe also because Vivienne visually gives extra space between the V's, and also because Vivian and Evans have almost identical endings, which makes them look a tad too similar). About Vivienne vs. Vivian, must Vivienne be pronounced with the ending emphasized? I've always pronounced it the same as Vivian, but I could be incorrect in doing so (I agree with above posters that the Vivian pronunciation flows better). Anyway, beautiful name choice and good luck!
