In the United States it is very much a matter of tradition within an individual family. We pay relatively little attention to the meanings of names. The choice of the name is made by the parents. I'm not sure why my parents named me "Daniel," but it is a good, solid, down-to-earth Old Testament name. Names that appear in the Bible are popular, and just a few examples would include, for men, Adam, Caleb, David, Joshua, Joseph, Solomon (Old Testament), John, Matthew, Michael, James (New Testament); for women, Esther, Judith, Naomi, Rachel, Sarah (often spelled "Sara" nowadays); Elizabeth, Mary, Martha. It is fairly common to honor an older family member by naming a baby after them. The usual pattern in the U.S. is "first name, middle name, last name," with the last name being the same as the father's, and the first and middle names being given by the parents. Commonly, speaking informally, people are called by their first name but it is not at all rare for someone to decide they like their middle name better than their first name and ask people to call them by their middle name. That's one of the reasons why you see names written in a form like "G. Gordon Liddy." People will say, and it isn't always a complete joke, something like "They named me after my uncle because they hoped he would leave money to me in his will, but they always called me by my middle name." People often name their children after famous people they admire. People often get creative and give their children names with unusual spellings, or simply make up a completely new name--that's more common with women than men. My last name is extremely common in the U.S. so we tried to pick slightly unusual names for our children so they would not encounter too many people with exactly the same name as they have.

In the US it varies. Most often, parents just choose a name that they like. Often parents name their children after another family member (for example, a grandmother). Less often, parents name their child after a historical figure (such as a character in the bible). I was named after my father's best friend who had recently died in war.

Women often take their maiden name as a middle name when they get married (and in modern times many keep their maiden name as their last name). The mother of Lyndon Baines Johnson is an example: Rebekah Baines Johnson. Nor is it uncommon to use the mother's maiden name as the middle name of her child, as was done in Lyndon's case. Another example of that is John Fitzgerald Kennedy (Fitzgerald was his mother's maiden name). Myself, I was given my father's first name as my first name, and the first name of my mother's father as my middle name.

As others pointed out, parents are given extremely broad latitude in choosing names for their children. There's a good wikipedia article about that subject here: https://en.wikipedia.org/wiki/Naming_in_the_United_States There has recently been some controversy in the United States about discrimination against people whose names as associated with a particular racial or ethnic group. Over the course of the last few decades, many African Americans have started giving their children first names that distinctly different from standard Anglo-American names. This practice came about as part of the so-called "Black Pride" movement that started in the 1960s. There's a list of the top "White" names and top "Black" names here: http://abcnews.go.com/2020/top-20-whitest-blackest-names/story?id=2470131. One context in which the controversy about discrimination against people with "Black" names has arisen concerns Airbnb bookings. Recent scientific experiments show that people with "Black" names have a harder time booking a room through Airbnb. See http://www.benedelman.org/publications/airbnb-guest-discrimination-2016-09-16.pdf Airbnb is actively working to combat that kind of discrimination.

my country is not an English speaker but we do speak English because it our second language. commonly, in our country we give names through the combination of our parents name.
