Rudy Giuliani married Regina Peruggi in 1968, who was his second cousin. They were married for 14 years before their marriage was annulled. Rudolph William Louis Giuliani is an American attorney, cybersecurity advisor, and politician, who was born on May 28, 1944. He has been married three times. Giuliani was first married to Regina Peruggi in 1968 for 14 years. Then he was married to Donna Hanover in 1984 for 20 years. Then his third marriage was to Judith Nathan in 2003 for 15 years.

In 1968, he married his second cousin, Regina Peruggi, who was the daughter of his father's first cousin. In 1975, they had agreed to a trial separation. Their marriage legally ended in two ways - a civil divorce was issued by the end of 1982 and with Roman Catholic church annulment. The Catholic Church annulled it because the couple had not obtained a church dispensation required when second cousins marry. According to the New York Times, he said he was under the impression that they were third cousins because he never calculated consanguinity lines.
