[1] She was born January 21, 1905, the daughter of Katharine W. De Forest (1888-1975), a writer for Harper's Bazaar, and John Logan (1875-unknown).

Her mother later married John M. Liesch, a World War I veteran and US Army sergeant, and both are buried in Arlington National Cemetery.

[4] She appeared in Solomon's Son (1912), Half a Chance (1913), The Wager (1913), Diversion (1913), The Dream Home (1913), His Fireman's Conscience (1914), and Under the Gaslight (1914).

[12][13] Her first name is often misspelled Rosanna (in IMDB, Ancestry, and some film reference books and movie magazines), but it was consistently spelled Rosana in her publicity photos, in the New York Times announcement of her first marriage, and on official documents.

Some sources give her birth date as 1907 rather than 1905, and either she or her parents may have lowered her age by two or more years for the demands of the film industry.
