Keep in mind that masculine plurals in Spanish can refer to mixed groups of males and females. Thus cuatro hijos can mean either "four sons" or "four children," depending on the context.
And while it may sound strange to the ear attuned to English, padres is a grammatically correct way to refer to both of one's parents. Also note that the word pariente means "relative" in general; it doesn't refer only to parents.
Here are the names for the most common relatives and some of the uncommon ones:
- padre: father
