I have the civil records from my ancestral village of Armento in southern Italy from 1809 - 1910 and there were many Ierardis. They married into my family, the Catoggios, numerous times. I have info on the Ierardis in the Armento area, but not familiar with the town you mention. I think I recall one Ierardi was the mayor of Armento for awhile. If you are on Facebook, there are some Ierardis you could contact. Let me know if you establish a connection to the Armento line. Wendy Harper Orlando
