Kids get their dad's last name primarily due to deep-rooted patriarchal traditions in Western societies, where historically men headed households and passed down lineage, with the surname signifying legitimacy and inheritance. This patrilineal custom became a powerful default, even as social norms evolve, often continuing because it's the easiest path, reinforcing male identity and family continuity over maternal lines, although many families now choose different options like hyphenating or using the mother's name.
Historically, the practice of children taking their father's last name stems from patriarchal traditions that emphasise paternal lineage and male dominance in family hierarchies. This custom originated in Western societies where women and children were often considered the property of the male head of household.
The most common cultural practice is for children to be given the father's name, if he's involved in their life. Single mothers often give their child their own last name. Gay couples (where there's two fathers or none) tend to make that decision for themselves, without any set convention.
Women traditionally took their husband's last name because of coverture, a legal concept erasing their identity. Despite historical origins, about 80% of women today still choose to take their husband's last name.
In the United States, researchers found that heterosexual married couples give the baby the father's name more than 95% of the time. The situation in the United Kingdom is similar – a recent study found that only 4% of families give children the mother's last name.
There isn't one single "rarest last name" globally, as rarity changes by region, but some names are incredibly scarce, with examples including Pober, Mirren, Febland in England, Gambello (around 60 globally), and unique historical names like Marsvin (Danish noble, extinct male line) or names that have nearly vanished like Twelvetrees or Birdwhistle. Rarity often comes from geographic origins, recent migration, or names dying out, with some existing with only a handful of people.
Choosing your child's surname
Your child can take the surname of either parent, or both. Even if you are not married and the father doesn't attend the birth registration, you can still give your child the father's surname.
You will face judgement from others. Although it's getting more popular, keeping your maiden name is still not the 'done thing'. Older generations in particular may consider this move unusual, or even disrespectful to your husband. You'll constantly have to remind people that you're married.
The Bible here emphasizes the sacrificial love that Christ demonstrated for his bride, the Church. Just as the Church is united with Christ and bears His name, so too does a woman, upon marriage, enter into a new spiritual union and take her husband's name.
Not at all! A hyphenated last name etiquette is about personal choice and respect for both partners. It's a modern way to honor both families and create a shared identity.
Baby gets the dad's/partner's name
Pros: The default choice in the United States is to give your child the last name of their father. This tradition is practiced by parents in a variety of situations – including heterosexual couples, same-sex couples, couples who adopt, and couples who choose not to marry.
(eBook available here: Ripley's Believe It or Not!) "The oldest surname in the world is KATZ (the initials of the two words - Kohen Tsedek). Every Katz is a priest, descending in an unbroken line from Aaron the brother of Moses, 1300 B.C."
Before Prince William and Prince Harry got married to Kate Middleton and Meghan Markle, respectively, the brothers used a surname that honored their father King Charles III's former royal title. The royal family has a history of adopting different surnames.
With a few exceptions, most states allow parents to choose their child's name, without restriction. Unmarried partners can decide to choose one parent's last name, hyphenate both last names, or create a new last name that combines both parents' names.
Patronymic surnames are family names that come from a male first name (forename). They often (but don't always) end in 'son', which can make them easier to spot. Some examples of patronymic English surnames are Davidson (the son of David) and Richardson (the son of Richard).
In some cultures in the past, matronymic last names were often given to children of unwed mothers. Additionally, if a woman was especially well known or powerful, her descendants might adopt a matronym based on her name.
Asia
Last names or family names likely had their origin England about 800 years ago, but this was not common in Jewish cultures in the days of Jesus. However, there were sometimes distinctions made for individuals based on their city of origin or residence. Jesus was sometimes referred to as "Jesus of Nazareth".
The Biblical Definition of Marriage
The Bible defines marriage as a sacred union between one man and one woman, established by God (Matthew 19:4-6). This relationship is a lifelong commitment, rooted in faithfulness and mutual love.
Mrs. is the proper title for a woman who was or is married, whether she has taken her spouse's last name or not. If you know the woman is married, Mrs. is the way to go.
Legal & Administrative Hurdles
Keeping your maiden name means you'll need to prove your marital status more often. For instance, if you're traveling with your spouse and your last names don't match, you might need to carry a marriage certificate to avoid issues.
Generally, there are no set rules or etiquette when it comes to deciding exactly how your hyphenated last name will read. You can go the "traditional" route and list your maiden name first, or you could choose to list your new last name first, followed by your original last name.
The couple must decide on the last name for their child. Unmarried couples are not required to assign a specific surname at birth. The child may carry the mother's surname, the father's surname, or a hyphenated surname. The chosen name will appear on the newborn's birth certificate.
An illegitimate child may carry his or her father's last name by virtue of RA 9255 or the Act Allowing Illegitimate Children to Use the Surname of their Father.
In most cases, when you want to change your child's surname, both parents will need to give consent. This is because both parents share parental responsibility under the Family Law Act. (Recent amendments have eliminated the presumption of 'equal shared parental responsibility' but shared responsibility still remains.)
