His friend, the critic Eugène Montrosier, arranged an introduction and from then, she and Félix were inseparable. They were engaged for two years before they married on August 5, 1869[5], despite her mother's opposition.[6] In 1870 they had their only child, Pierre[5]. Because of the scarcity of good medical care during the War of 1870 and the Paris Commune, Bracquemond's already delicate health deteriorated after her son's birth.[6] Much of what is known of Bracquemond's personal life comes from an unpublished short biography authored by her son entitled La Vie de Félix et Marie Bracquemond.[4]
