Traces of the family are found in the placenames of the north and west, with Ballymacanally in Magheralin parish in Co. Down, Cahermacanally in Killursa in Co. Galway and Tanmacnally in Ematris in Co. Monaghan. Occasional variants of the name have included MacAnnuly, MacAnnulla, Knally and Manally.
