Question: Who won the most doubles Grand Slam titles, Virginia Wade or Jorge Lozano?
Context: Kenneth Robert Rosewall {'1': ", '2': ", '3': 'AM, MBE', '4': "} (born 2 November 1934) is a former world top-ranking amateur and professional tennis player from Australia.  He won a record 23 tennis Majors including 8 Grand Slam singles titles and before the Open Era a record 15 Pro Slam titles and a record 35 Major finals overall.  He won the Pro Grand Slam in 1963.  Rosewall won 9 slams in doubles with a career double grand slam.  He is considered to be one of the greatest tennis players of all time.  He had a renowned backhand and enjoyed a long career at the highest levels from the early 1950s to the early 1970s.  Rosewall was one of the two best male players for about nine years and was the World No. 1 player for a number of years in the early 1960s.  He was ranked among the top 20 players, amateur or professional, every year from 1952 through 1977.  Rosewall is the only player to have simultaneously held Pro Grand Slam titles on three different surfaces (1962–1963).  At the 1971 Australian Open he became the first male player during the open era to win a Grand Slam tournament without dropping a set. Sarah Virginia Wade, (born 10 July 1945) is a former professional tennis player from Great Britain.  She won three Grand Slam singles championships and four Grand Slam doubles championships, and is the only British woman in history to have won titles at all four Grand Slam tournaments.  She was ranked as high as No. 2 in the world in singles, and No. 1 in the world in doubles. The 1968 US Open (formerly known as U.S. National Championships) was a tennis tournament that took place on the outdoor grass courts at the West Side Tennis Club, Forest Hills in New York, United States.  The tournament ran from 29 August until 8 September.  It was the 88th staging of the tournament and the fourth Grand Slam event of 1968.  It was the first edition of the tournament in the Open Era of tennis and as such for the first time offered prize money, totaling $100,000.  Arthur Ashe and Virginia Wade won the singles titles.  Ashe was still registered as an amateur and therefore not entitled to the $14,000 first-prize money, which instead went to runner-up Tom Okker, while Wade earned $6,000.  Frank Parker, at the age of 52, lost to eventual champion Arthur Ashe in the second round, and still holds the record for the oldest man to compete in a Grand Slam singles tournament. The Williams sisters are two professional American tennis players: Venus Williams (b. 1980), a seven-time Grand Slam title winner (singles), and Serena Williams (b. 1981), twenty-three-time Grand Slam title winner (singles), both of whom were coached from an early age by their parents Richard Williams and Oracene Price.  There is a noted professional rivalry between them – between the 2001 US Open and the 2017 Australian Open tournaments, they met in nine Grand Slam singles finals.  They became the first two players, female or male, to play in 4 consecutive grand slam singles finals from the 2002 French Open to the 2003 Australian Open; Serena famously won all 4 to complete the first of two "Serena Slams".  Between 2000 and 2016, a 17-year span, they collectively won 12 Wimbledon singles titles (Venus won 5 and Serena won 7).  By winning the 2001 Australian Open women's doubles title, they became the 5th pair to complete the Career Doubles Grand Slam and the only pair to complete the Career Doubles Golden Slam.  At the time, Venus and Serena were only 20 and 19 years old, respectively.  Since then they have gone on to add another two Olympic gold medals in the 2008 Beijing Olympics and the 2012 London Olympics.  Nearly a decade later, the duo would go on to win 4 consecutive grand slam doubles titles from 2009 Wimbledon through 2010 Roland Garros, which would catapult them to co-No.  1 doubles players on 7 June 2010.  Two weeks later, on 21 June 2010, Serena would hold the No. 1 singles ranking and Venus would be right behind her at No. 2 in singles.  Their most recent grand slam doubles titles came at the 2012 Wimbledon & 2016 Wimbledon events.  They remain very close, often watching each other's matches in support, even after one of them has been knocked out of a tournament.
