or she may have up to four surnames in any order desired picked up from the total of his/her parents and grandparents' surnames). The use of any surname outside this lot, or of more than six names, is legally possible, but it requires dealing with bureaucracy. Parents or the person him/herself must explain the claims they have to bear that surname (a family nickname, a rare surname lost in past generations, or any other reason one may find suitable). In Brazil, there is no limit of surnames used. In general, the traditions followed in countries like Brazil, Portugal and Angola are somewhat different from the ones in Spain. In the Spanish tradition, usually, the father's surname comes first, followed by the mother's surname, whereas in Portuguese-speaking countries the father's name is the last, mother's coming first. A woman may adopt her husband's , but nevertheless, she usually keeps her birth name or at least the last one. Since 1977 in Portugal and 2012 in Brazil, a husband can also adopt his wife's surname. When this happens, usually both spouses change their name after marriage. The custom of a woman changing her name upon marriage is recent. It spread in the late 19th century in the upper classes, under French influence, and in the 20th century, particularly during the 1930s and 1940, it became socially almost obligatory. Nowadays, fewer women adopt, even officially, their husbands' names, and among those who do so officially, it is quite common not to use it either in their professional or informal life. The children usually bear only the last surnames of the parents (i.e., the paternal surname of each of their parents). For example, Carlos da Silva Gonçalves and Ana Luísa de Albuquerque Pereira (Gonçalves) (in case she adopted her husband's name after marriage) would have a child named Lucas Pereira Gonçalves. However, the child may have any other combination of the parents' surnames, according to euphony, social significance, or other reasons. For example, is not uncommon for the firstborn male to be given the father's full name followed by "Júnior" or "Filho" (son), and the next generation's firstborn male to be given the grandfather's name followed by "Neto" (grandson). Hence Carlos da Silva Gonçalves might choose to name his first born son Carlos da Silva Gonçalves Júnior, who in turn might name his first born son Carlos da Silva Gonçalves Neto, in which case
