After Amschel's death she got deep into horse breeding in the UK with her new husband:

It would be true, if a little misleading, to say that Anita Wigan has spent the last 27 years looking for the right man. Now she has found him. When The Right Man surged to victory in the Al Quoz Sprint at Meydan in March, he became the first horse bred by Wigan to win a front-line Group 1 race.

In 1993 Wigan bought The Right Man’s grandam Three Terns, a daughter of Prix de l’Arc de Triomphe heroine Three Troikas, for 19,000gns at Tattersalls. From Three Terns she bred and raced the Warning filly Three Owls, a winner at Brighton, whom she subsequently gave to her son-in-law, Ben Goldsmith, on his marriage to her daughter Kate.

When Wigan retrieved Three Owls she sent her to Lope De Vega. The consequence was The Right Man, whose triumph in Dubai was his seventh from 11 starts. There should be more to come from this lightly-raced five-year-old, who is very much on the march.

Her new-found fascination found expression at Rushbrooke, the Rothschild family estate near Bury St Edmunds where she lived with her late husband. And there she stayed until her son, James, moved to the US two years ago, in the process triggering Rushbrooke’s sale.

Her husband's "suicide":
