Anna van Egmont the Elder (1504–1574) was the mother of executed counts Horn and Montigny.
Unfortunately, this marriage remained childless, but he received permission to make his oldest stepson Philip de Montmorency become Count of Horn upon his death on the condition he marry Walburgis van Nieuwenaer, which he did.
[1] Anna's daughter Maria married in 1562 in Weert with Peter Ernst van Mansfeld, who later served the Duke of Parma, and daughter Eleonora married Antoine II de Lalaing, Count of Hoogstraten, who died 11 December 1568 as the result of a battle injury suffered while serving the army of William of Orange.
When the Duke of Alva arrived in the North to defend the interests of the Inquisition, Anna's son Philip was seized along with Lamoral and they were beheaded 5 June 1568 in Brussels.
