During the Second World War she was active in the sanitary section of the Women's Military Service in the area of Zduńska Wola and the Zapolice municipality.

On 13 March 1984, she entered into a second marriage with André Paul Eugène de Cayeux de Sénarpont.

Anne's husband, André Paul Eugène de Cayeux de Sénarpont, was born on 24 December 1907 in Paris and died on 27 December 1986 in Saint-Nazaire (Loire-Atlantique). He was the son of René de Cayeux de Sénarpont (born 1870) and Aline Philippe (born 1880). André de Cayeux was an eminent geographer, geologist and planetologist. He served as professor of geology at the Faculty of Sciences of Paris (1958-1969) and as scientific director of Laval University in Canada (1968-1974). He is known for his development of sand morphoscopy and as one of the fathers of the French school of planetology. He collaborated with scientists such as Jean Tricart and Audouin Dollfus. He received an honorary doctorate from the University of Lodz. From his first marriage to Anne Marie Antoinette de Lavenne de La Montoise (born 3 July 1908 in Cherbourg, died 26 May 1982 in Saint-Maur-Des-Fossés), he had 12 children. Their wedding took place on 4 August 1931 in Saint-Aignan-Grandlieu (Loire-Atlantique) (https://gw.geneanet.org).
