Her eldest son was betrothed to a daughter of Richard I of Capua in 1058, but died before the marriage could take place.
According to Amatus of Montecassino, Atenulf was consequently supported by Pandulf in taking the duchy of Gaeta from Asclettin, Count of Aversa, on the death of Ranulf Drengot in 1045. Richard extorted the morgengab anyway and Gaeta became a feudatory of Capua. As senatrix and ducissa of Gaeta, Maria ruled as regent for her and Atenulf"s son Atenulf II after her husband"s death on 2 February 1062.
On 1 June, a pact was confirmed between Maria and the counts of Traietto, Maranola, and Suio.
The allies were excluded from forming any pact with the Normans and sworn to protect the territory of the Gaetan duchy. The treaty was finalised at Traietto and was to last for a year.
The league was successful in preventing Richard of Capua from extending his conquests during the year. However, Richard skillfully negotiated to prevent a renewal of the pact and on 28 June 1063, he was in possession of Gaeta.
In February 1065, the revolted were put down by Richard of Capua and Maria and William were expelled from Gaeta.
