In Japan a family which has daughters but no sons may adopt the husband of one of the daughters. He will take on his wife's family's surname and the obligations of a born-to son to his parents-in-law. Such a husband is known as a muko yoshi, literally, an "adopted bridegroom." The same custom appears in many other cultures. For example, this is one interpretation of the Jewish Law of Zelophehad (see: Joseph the Carpenter).
