Twenty-two clusters were formed from the mortalities falling in the French Quarter. Of these, six had at least 5 French born members, and three had at least 5 Italian born members. The French clusters grouped together earlier in the epidemic (apart from cluster 9), while the Italian clusters occurred later, though again these were grouped together. Those clusters with an * also remain intact when only single nativity mortalities are considered in their creation (note cluster 6 actually splits into two).
