Gregan Spelling Variations

People who were accounted for by scribes and church officials often had their name recorded many different ways because pronunciation was the only guide those scribes and church officials had to go by. This resulted in the problem of one person's name being recorded under several different variations, creating the illusion of more than one person. Among the many spelling variations of the surname Gregan that are preserved in archival documents are Gormley, O'Gormley, Grehan, Gormleigh, Gormly, Gormlie, Grimes and many more.
