… summarised from Actualité juive (Jewish current affairs), Paris, January 24, 2002, a source which presumably does know:

ALTHOUGH the maiden name of Linda Lay is not known (she is the wife of Ken Lay, CEO of Enron — the most costly scandal since WTC, and Actualité juive insists that neither she nor her husband is Jewish, she was the yearly biggest donor of the Houston Holocaust Museum. Mrs Lay (i.e., Enron for at least half of the amount) would pay ten percent of the museum’s annual expenses running at $3 per year, i.e. $300,000. In March, the couple was due to preside over a gala fund-raising dinner for the museum, the guest of honour being George W Bush lui-même, the bretzel man.
