Double-barrelled Name - Written Form

Written Form

Many double-barrelled names are written without a hyphen (this can cause confusion as to whether the surname is double-barrelled or not). Notable persons with unhyphenated double-barrelled names include David Lloyd George (born with Lloyd as a middle name, but self-transformed into a double barrelled surname), the composer Ralph Vaughan Williams, Sir Winston Spencer Churchill, Helena Bonham Carter (although she said the hyphen is optional ), comedian Sacha Baron Cohen, former first lady Jacqueline Kennedy Onassis and Sylvia Llewelyn Davies.

One historic early aviator, Alberto Santos-Dumont, is known to have not only often used an equals sign (=) between his two surnames in place of a hyphen, but also seems to have preferred that practice, to display equal respect for his father's French ethnicity and the Brazilian ethnicity of his mother.
