The only genealogical information I can find is, "A3. Don Lorenzo (* Castellammare 12.VIII.1893 † ?), Nobile di Messina. = Roma 2.IX.1916 Elena Biondi
B1. Donna Maria Bianca (* Roma 7.IV.1919), Nobile di Messina. = Roma 7.IV.1937 Pietro dei Marchesi Bruno di Belmonte, divorzia”
From Carlo Raso's photostream on flickr; this image was heavily retouched with Photoshop to remove creases extending from the left edge into the center and remove strong veiling reflection on the right side that resulted in blurring her left hand and reconstructing the left-most fold of her skirt. Also posted to The Bustle Periods - 1870 to 1890 Album here.
