Robinson Genealogy

Peter Robinson of Northern Ireland is the first minister of the pro-British democratic Unionist Party. You don't often hear of a Robinson in Ireland. I wonder how far back his family goes in Ireland.
Update: 1/21/10: Today on NBC Peter's wife, Iris, made the news in a scandal. She had taken herself a young lover, who is not a willing partner. Peter has been married to Iris for a very long time and took time off his duties to work on this problem. He has decided to stay married to her. It sounds like she also needs to go for sex therapy, like Tiger Woods. All this on TV this morning as they played "Mrs. Robinson" lyrics in the background from The Graduate by Simon & Garfunkel from 1967's The Graduate with Anne Bancroft and Dustin Hoffman. The shot of Peter showed a very nice appearing man. This was a movie about another Mrs. Robinson who took a lover for herself, who was Dustin Hoffman, a new graduate. It sounds like both Mr. Robinsons had lost their zip. "And here's to you, Mrs. Robinson....____ loves you more than you will know-wo, w0, w0...G-d bless you please, Mrs. Robinson......."
