Joyce: I just happened to come across your entry and enjoyed reading it. Alan fitz Flaad was the Conqueror's agent if memory serves, begetting the Fitzalan families. Walter Fitzalan made it to Renfrewshire in the 1100's and became Steward of Scotland, later begetting the Stewarts. The Gaidhlig for the name is "ailein" and, alternatively, "ailean". This has been a study of mine as well. Thanx.
