As for boys names I am a bit of a sucker for some very Scottish names
e.g. Hamish, Angus, Cameron
When I was looking I found the national statistics site very useful - they list the top 100 names for the last five years.
www.statistics.gov.uk/specials/babiesnames_boys.asp
I found it useful because I didn't want a name that was too popular, although I still wanted something traditional. (We went with Robin in the end for our little boy.)
