On another message board was a very good synopsis.copy of text: "From Woulfe's,"Irish Names and Surnames" O'Duibeannay -Irish O'Doveanna, O'Devenie, Devanny, Devaney, Devany, Devenny, Devenney, etc. Descendent of Dubeannay perhaps Black of Eanac (a place name); the name of a Co. Down family... Also, from Edward MacLysaght, "More Irish Families", O'Gorman Ltd., Galway and Dublin, 1960. O'Devany , Devenney The mention of this name immediately calls to mind one of the best known of Irish Catholic martyrs, Conor or Cornelius O'Devany , Bishop of Down and Conor from 1582 to 1612, whose capture, torture and execution are described at unusual length by his contemporaries the Four Masters. In the many records and commentaries which deal with his case his name is written in a number of different ways: O'Devany, O'Dovany, O'Deveney, O'Devenny, etc. in English, all still extant in Ireland or America - but usually without the prefix O - while in Irish he is called both O'Duibheannaigh and O' Duibheamhna. According to Woulfe these are distinct names, the former of Co. Down, the latter being that of the ancient chiefs of Ui Breasail in Co. Armagh; but O'Donovan places O'Duibheamhna in Co. Down near Lough Neagh. It is open to doubt weather these are two separate septs at all, but we can be sure that, weather of the stock or not, they belonged to east Ulster. The fame of one member has imparted a disproportionate importance to the Ulster sept to which he belonged. It must be remembered that there is another - in this case unquestionably distinct - sept called Devany, etc in English. This is O' Dubhanaigh of Connacht and Donegal. As Devenny it is often met with in the records of the Diocese of Raphoe; Matheson's modern statistics show it to be most numerous in Mayo and Leitrim. It is reasonable to conclude that the O'Devannys pardoned with Rory O' Donnell and his followers in 1602, the O' Devennys of Raphoe were all of this sept, which was formerly of Donegal rather than of Connacht. Another difficulty arises in connection with the name Devany in Connacht. Devane and even Devine have been recorded as synonyms in the birth registration returns for Mount Bellew and other places in Co. Galway."
