Couples give many reasons for choosing to blend their surnames. • Couples may choose to adopt a blended name to enter into marriage "with a completely new start without any history being tied to their surname". Name blending confers the same surname upon both spouses. This allows the family to conform to the expectation that the family (and any children) will all share the same name, and avoid confusion that can arise when spouses retain differing surnames. • Name blending avoids hyphenation and the complications associated with having a
double-barreled surname or other form of combined name that may be too long for use in some circumstances (for example, many computer databases limit last names to 16 characters). • Name blending avoids
exponential growth in the length of surnames caused by successive double-barrelling. • Name blending often creates a unique surname. With over 1 billion internet users, having a unique last name can make it easier for people to find an individual using search engines. It also increases the chance that the name will be available as a username in e-mail systems and online communities. • Name blending allows a single surname to acknowledge the diverse background of the family. • Name blending also provides an alternative for
same-sex marriages, where there are not longstanding traditions regarding the taking of one participant's surname by the other. == Names used to refer to celebrity couples ==
