DS1 - Bob (a old joke about naming a child bob) or Zermatt (as in town in Switzerland where we visiting during some of our TTC time - sharing a dorm with two other couples and had to make obvious excuse to get some privacy to BD!)

DS2 - Ester (as that is what my mother and sister wanted us to call No 2 but wasn't going to happen).

We found out the gender at the 20 week scan and chose proper names then, so we just used their actual names from then on. Not very exciting.
