The Gregorian chant developed in western and central Europe around the 9th and 10th centuries. Some credit Pope Gregory the Great with developing the chant but scholars believe it is more a combination of Gallican and Roman chant with Carolingian synthesis.
Pope St. Gregory the Great is the patron saint of singers and choirs because he is the one who compiled and advanced Gregorian Chant (named after him).
Pope Gregory I the Great is the pope you are referring to. He did not write Gregorian Chants. He compiled and cataloged the plain songs that were used in liturgies at the time. Later they became known as Gregorian Chants.
The Gregorians are not a specific set of people. Most things referred to as Gregorian relate to the influence of Pope Gregory I. For example, the Gregorian chant is a type of song in the Roman Catholic Church associated with the Pope.
