In 1835, an extremely attractive Polish count, the twenty-three year old Ignatius Gurowski (1812–1887), moved into Custine and Saint-Barbe's home in the rue de La Rochefoucauld to form a ménage à trois. Wrote Custine: "He has an excellent heart, an original mind, is graciously ignorant of everything, and what settles it all, a charming bearing and countenance." The capricious Gurowski was not an easy guest, running up debts and seducing both men and women, but appears to have amused the couple. The detailed register of homosexuals, then maintained by the Paris police prefecture, and which termed Custine's inclinations 'frantic', wrote of Gurowski with a comical note of possible despair: "It is hereditary in his family: his father and grandfather were of the same religion." In 1841 Gurowski married a Spanish infanta Isabella Ferdinanda de Bourbon.
