Yes to both things you raise!
The vast majority of the victims of the Genocide of 1915 were Armenian Orthodox, to be sure.
Blessed Ignatius Maloyam was also martyred along with over 300 (?) Armenian Catholic members of his Archeparchy. I wonder why these were not beatified as well?
The more ancient Christian tradition is to canonize all those who have been martyred - rather than to choose one or just a few for this honour.
Also, "Beatification" is simply a Latin Church thing that does not obtain in the Eastern Churches. The Eastern Churches have local canonizations meaning liturgical veneration of a saint in a specified locale. That locale widens later as the veneration of the saint grows until the cultus takes on national and then universal status. The term "Blessed" (which Eastern Catholics have adopted because Rome told them to
) in the East is synonymous with "Venerable" in the West.
It would be good if His Holiness would extend the cultus of "St Ignatius the Hieromartyr" to the Western Church next month . . .
