Before wedding, a prenuptial agreement was composed that shared a life lease of the estate between husband and wife, transferred after their death to children. The Morrises became pillars of the local establishment since Roger Morris was appointed on the Governor's Council of the Province of New York. The following year after his marriage, Morris had a large country estate named "Mount Morris" (today the Morris-Jumel Mansion) built in northern Manhattan between the Hudson and Harlem rivers in what is now the Washington Heights neighborhood. Situated on Coogan's Bluff, its vista included lower Manhattan, the Hudson and its Palisades, the Bronx, Westchester, the Long Island Sound and the Harlem River.
