What can freddie be short for?

[dietcoketime69]

Apart from Frederick, Alfred or Wilfred?

Frederico/Federico
Manfred
Alfredo

Federica (girl I knew)
Winifred
Freda

DP has helpfully pointed out Freddie is as long as Wilfred and longer than Alfred...

Bilfred (real but very rare)
Fredo

Siegfried

Fredegar (LOTR)

Friedrich
Fridolin
Winfred

Andrew, apparently, if your surname is Flintoff!

At a stretch:

Gottfried/Godfrey
Fremont
Friedan
Fridmar
Fridmund
Fridolf
