Del Puente I

The marquis del Puente, a Spanish gentleman Marie meets at Spa in the summer of 1874; the diary's «Del Puente I» is the tag for the single man. The Mon Journal t.4 index has «Puente (marquis del)» on pp. 20, 42–43, 54, 67, 78, 91, 107, 154 (the Spa and Paris weeks).

Diary

• Spa, 1874-07-24 (022.0005): in the evening group at the Spa casino, «Le marquis de Puente, M. Clark : voilà notre coin», next to M. Jurybarren («beaucoup plus singe que Fedus»).
• 1874-07-29 (022.0202): «Ce soir les Espagnols, sous la conduite du marquis del Puente, organisent un cotillon pour leur société.» On 08-03 (022.0373) he is among those who watch Marguerite's arrival; on 08-08 (023.0023) he and Jurybarren, «l'adoration de Walitsky», have left Spa.
• 1874-08-19 (023.0227): Walitsky mocks «Moïse Jurybarren», del Puente and the small man who resembles Rodionoff, calling them carlistes (the Third Carlist War was then being fought in Spain, 1872–1876: Wikipedia «Third Carlist War»), «surtout après la société particulière et le cas que Paul faisait de Jurybarren et de del Puente pendant les affaires du cotillon».
• Paris, 1874-09-24 (024.0090): on a drive in the Bois, «une revue de nos Spadois, Ostendais et Niçois. Le célèbre del Puente !»

His first name and his connection with the Spanish nobility were not found. Mon Journal's Spa passages show the group as young Spaniards who dance and run the Spanish cotillions at the Casino.
