As predominately Christian countries, a lot of people get named Jon, David, and Mary, so there's little difference. Though I met a lot of Niall's when studying in the UK.
Grace, Ruby, Olivia, Emily, Jessica, Jack, Thomas, Oliver, Joshua, Harry, Charlie, Daniel etc are some of the popular baby names in uk.Jacob,Michael,Ethan,Joshua,Daniel,Christopher,Anthony etc are popular names in US
