en.wikipedia.org/wiki/Mark_Madoff

This sentence gets the year of Mark Madoff's marriage to Stephanie Mikesell wrong.

Multiple independent sources place the marriage in 2004, not 2003:

• A 2012 bankruptcy-court decision states: "Stephanie Mack was married to Mark Madoff from October 2004 until his death in 2010."
• ABC News, in an interview-based report centered on Stephanie Madoff Mack, says: "Stephanie, then 30, married Mark Madoff ... in October, 2004."
• Harper's Bazaar likewise reports: "The two married on Nantucket in 2004."
• The Google Books author bio for Stephanie Madoff Mack's memoir says she is the widow of Mark Madoff, "whom she married in 2004."

Because these sources consistently place the marriage in 2004, the article's claim that he married Stephanie Mikesell in 2003 is factually incorrect.

The article says Mark Madoff joined his father's company in 1987, but multiple sources place his start at Bernard L. Madoff Investment Securities in 1986.

Evidence:

• A filing in the Madoff trustee litigation states: "Mark Madoff, Madoff’s son, joined BLMIS in 1986 after graduating from college."
• Another trustee filing says: "From the time he graduated from the University of Michigan in 1986 through his father’s arrest in December 2008, Mark Madoff worked at BLMIS."
• Contemporary reporting also states that he graduated from the University of Michigan and joined his father's firm in 1986.

Because these sources consistently place his start at BLMIS in 1986, the article's statement that he joined in 1987 is incorrect.
