Will and Estate: Wellington had a strange will that contained a spite clause to avenge a family feud. The clause said that the bulk of his fortune could not go to any descendants until 21 years after both his children and grandchildren passed away. Those conditions were met in 2010 when 12 of his descendants received the estate which was worth around $100 million. Burt owned most of the Ann Arbor Railroad system at one time and bought railways in China and Russia.
