December1984:We haven't discussed names with anyone other than my mum. Partly because I didn't want peoples' comments to affect our choice and also because what with having 3 other babies due in the family in the two months before ours, I didn't want to run the risk of anyone pinching our names

Exactly this! My Mum and Dad know our shortlist but we still have to decide an actual name! There were a couple of groans at some of the names, but they loved the girls names thankfully! Girls names will be one of two now, boys proving a bit trickier!
We have 2 relatives due around the same time, 1 in Feb and the after us in May, but they have found out the sex so more than likely already have their babies named like they did last time!
My faves are Liberty and Luca from your list, but go with what suits YOU and OH, not what others like! xx
