I was recently working on a project which needed me to filter some descriptive text in Excel, removing all forenames and surnames (programatically). Clearly this needs a list of ‘target’ names to find and remove; Google search results were a bit weak, so I thought I’d note down the resources I eventually ended up using:

UK Office for National Statistics – Top 100 Baby Names Historical Data:

As an aside, there are a few US-oriented sites out there too, along with a Stackoverflow thread which got me started on this:
