Stijn, Gijs, Thomas, Niels, or Pepijn

We're looking for a timeless name for our second baby. The gender is unknown, which is why we're creating two polls; one for a boy's name and one for a girl's name.

We have the following requirements: Dutch, easy to spell, not too popular but also not unique, max 2 syllables. We have a daughter named ANNE. This is a good example of our 'requirements list'; we consciously chose Anne instead of Anna, because Anna was so trendy. Because our daughter is named Anne, we'd like a name that does NOT start with an A. Preferably no names starting with an R either, because my partner and I are named Rens and Romy. The middle name and last name fit all the names.

Which name do you think fits best so far? Other names are also welcome, because we still have a bit of time.
