Marie Fabbri married Count Giuseppe Ludolf, brother of her sister Ernestine's husband, Count Uberto Ludolf.
She apparently had no children and was widowed at the time she played hostess to Cornelia Randall Holland during her visit to Italy in 1937, and was the last of the Fabbri cousins overseas to keep in touch with the Hollands by letter.

Here she stands in the doorway of her villa, Poggio Marino, at
I Ronchi, with her mother, Sara Ann Fabbri, in 1930.
