Kings' real names

[denisegordon]

Why did George 6th not use his real name of Albert and Edward 8th (for a short time) not use his real name of David when they became kings?

According to a similar question in The Guardian's Notes and Queries http://www.guardian.co.uk/notesandqueries/query/0,
5753,-14156,00.html the monarch is apparently allowed to choose which name they like. (However, the reasons behind their choice are not always clear, although it is rumoured that Charles may use a different name since the two previous King Charles's didn't do particularly well.)
Incidentally, Edward VIII's real name wasn't David, it was actually Edward Albert Christian George Andrew Patrick David - so although he was known as David, he used his real name when he became King. For other real names of monarchs, see Debrett's http://www.debretts.co.uk/royal_connections/kings_
and_queens_of_britain.html

Prince Charles has stated a preference for 'George VII', in honour of his grandfather, George VI as was. His actual names are Charles Philip Arthur George.

We had not had a King Albert. To have one would be a break with tradition to appoint one. Albert was the German -born consort to Queen Victoria. There were two good reasons therefore for the future George VI not to chose Albert at a time when there was a war with Germany already in prospect and a war with Germany had ended less than 20 years before.
