Portuguese names are derived from Latin names most often, but could also include Greek, Celtic, Arabic, and Germanic influences. Portuguese babies often have two given names, followed by the mother’s paternal family name and then the father’s paternal family name. Names are often religious in nature and reflective of Catholicism’s influence in the region. Nicknames for girls usually add -inha to the given name and nicknames for boys usually add -inho to the given name. These nicknames can often last throughout their lives. Of note, Maria is a common first name for a girl and a common second name for a boy.Click on a name to find the name meaning, popularity, origin and other useful information.
