After much squabbling, DH and I have stumbled on a name for DS2 that we both actually like - Theo. No mean achievement given DH's tastes usually run to things like Thor or Marmaduke (I kid you not), whereas I prefer slightly more normal names (not Tom, Edward and the like, but names like Laurence, Alistair and so on).
Unfortunately, one of our friends has a 3 year old called Theo, and we would both feel uncomfortable about "copying" her. We see this friend and her DC about every 3 months, do occasional joint holidays and have a reasonable circle of mutual friends.
So, any suggestions for alternatives to Theo? I'm actually not wild about the name Theodore (but would prefer to give the long version of a name on a birth certificate and could probably live with it). DH and I have vaguely agreed on Alexander as a fallback name if we can't come up with anything better, but we're both a bit meh about it (no offence to anyone with DC called Alexander; it's a perfectly nice name).
DS1 is called Hector. If DS2 had been a girl, name would probably have been Iona.
