Giacomo Cantelmo

[1] The family's surname is sometimes given as Cantelmo-Stuart because they claimed a relationship to James II of England.

[1] Pope Innocent XI named him abbot in commendam of San Antonio di Vienna in Naples.

[1] In the consistory held on 13 February 1690, Pope Alexander VIII created him a cardinal priest.

On 10 April 1690 he attended Joseph's coronation as King of the Romans; on the same day he received the red hat, was awarded the titular church of Santi Marcellino e Pietro al Laterano and named papal legate to Urbino.

The new pope named him Camerlengo of the Sacred College of Cardinals, with Cantelmo serving from 3 February 1700 to 23 January 1702.
