Baby Name Poll Results

We are now absolutely, definitely down to the last 2 names for our second son (first son is Lachlan). We are of Indian background, hence the last name. We originally thought Lucas, but it is very common these days. We have heard people have mixed thoughts about Harvey, but it is apparently making a bit of a comeback, and we thought it matches Lachlan nicely. It is in the top 100 in the UK (and in the top 1000 in the US). We are in Australia, so our popular names tend to come from both the UK and US, but leaning towards the UK. Should we go a very common name like Lucas, or something a little unusual (and that some people may not like), like Harvey? Let us know your thoughts please!
