Mac Cana

[3] The Mac Cana originated as chiefs of Cenél Aengusa, the name of a kindred and its territory in Tír Eoghain.

[4] In the 12th and 13th centuries they extended their lands along the south of Lough Neagh where they gave their name to the territory of Clancann (Clann Chana),[4] later the barony of Oneilland West.

[4] Nearby Portadown (Port an Dúnáin) is believed to be named after a fort of the Mac Cana.

[5] An English map from the early 1600s shows a prominent house at Maghery in Clancann, which was probably the last residence of the Mac Cana chiefs.

[5] Irish rebels killed about 100 captured British settlers at Portadown by forcing them off the bridge into the River Bann, and shooting those who tried to swim to safety.

The Mac Cana had become chiefs of Oneilland (highlighted) by the 16th century
