You are correct! Mac Dhomhnuill would have originally been pronounced more like MAC GOAN-ILL. Like most Gaelic names, it was sloppily rendered into English.

Connell is almost always from the Irish Ó Conaill or more rarely, Mac Conaill. It should be noted, however, that many Irish migrated to Scotland in the mid-19th Century, and Irish names are quite common particularly around Glasgow.
