Grillo's wife Rosemary had a long term affair with Neil Dellacroce which resulted in 2 or 3 children. When Grillo found out about the affair from other mobsters,he would have been well within his rights to demand Dellacroce's death, since they were both made guys. As the story goes,Grillo was persuaded to accept a large cash settlement instead,because of the respect and clout that Neil had.After that,the affair ended. As a side note,when Carlo Gambino chose his successor,he remembered the affair,and as a measure of his disfavor passed over Neil in favor of Castellano.Also,John Gotti,Sr. was involved in an affair with Shannon Grillo,one of Neil and Rose's kids.Just to show the sheer brass that Dellacroce had,even after the affair was over,he still had his home phone listed under E. Grillo.
