Family names or surnames are also often used as given names.

Family names, surnames, or last names were first used in the Middle Age and commonly referred to an individual's profession. Other ordinary surnames originated or start from the father's first name to which son was included, such as Robertson, Stevenson, Richardson, or Davidson.

Last names or surnames were given or created in many countries using distinct arrangements. A few countries used occupations. Others made use of family names. The use of 'O' at the start of names usually means "grandson of" (and not, as is commonly accepted, son of ). For example, the name O'Ryan would usually mean 'Grandson of Ryan.' The O prefix has an Irish base. Some popular Irish last names are O'Sullivan, Murphy, McCarthy, Byrne, O'Connor, Walsh, Ryan, and Kelly.
