They

pronoun, plural in construction Etymology: Middle English, from Old Norse their, masculine plural demonstrative and personal pronoun; akin to Old English thæt that 1. a. those ones — used as third person pronoun serving as the plural of he, she, or it or referring to a group of two or more individuals not all of the same sex Example: they dance well b. he I,2 — often used with an indefinite third person singular antecedent Example: everyone knew where they stood — E. L. Doctorow Example: nobody has to go to school if they don't want to — N. Y. Times 2. people 2 — used in a generic sense Example: as lazy as they come Usage: They used as an indefinite subject (sense 2) is sometimes objected to on the grounds that it does not have an antecedent. Not every pronoun requires an antecedent, however. The indefinite they is used in all varieties of contexts and is standard. Usage: They, their, them, themselves: English lacks a common-gender third person singular pronoun that can be used to refer to indefinite pronouns (as everyone, anyone, someone). Writers and speakers have supplied this lack by using the plural pronouns Example: and every one to rest themselves betake — Shakespeare Example: I would have everybody marry if they can do it properly — Jane Austen Example: it is too hideous for anyone in their senses to buy — W. H. Auden. The plural pronouns have also been put to use as pronouns of indefinite number to refer to singular nouns that stand for many persons Example: 'tis meet that some more audience than a mother, since nature makes them partial, should o'erhear the speech — Shakespeare Example: a person can't help their birth — W. M. Thackeray Example: no man goes to battle to be killed. — But they do get killed — G. B. Shaw. The use of they, their, them, and themselves as pronouns of indefinite gender and indefinite number is well established in speech and writing, even in literary and formal contexts. This gives you the option of using the plural pronouns where you think they sound best, and of using the singular pronouns (as he, she, he or she, and their inflected forms) where you think they sound best.
