Question: Between the tennis players, Carly Gullickson, and Pierre Barthès, which is of French nationality?
Context: Pierre Barthès (born 13 September 1941) is a French retired professional tour tennis player. Carly Gullickson and Nicole Kriz were the defending champions, but decided not to participate this year. The history of tennis in New Zealand dates back to the 1870s, the decade when the development of modern tennis began.  The first "New Zealand Tennis Championships" were played at Farndon in Hawkes Bay in 1886.  New Zealand Lawn Tennis Association (NZLTA) was formed at a meeting held in Hastings in December 1886.  Shortly after its inauguration, the New Zealand Association became affiliated with the Lawn Tennis Association (England).  In 1904 New Zealand Lawn Tennis Association amalgamated with six Australian state tennis associations to form the Lawn Tennis Association of Australasia.  New Zealand Lawn Tennis Association played a significant role in the origin of the Australian Open.  Lawn Tennis Association of Australasia created the tournament called "The Australasian Mens Championships" (which later became Australian Open) in 1905 and was first played in Warehouseman's Cricket Ground and it was decided that championships would be hosted by both Australian as well as New Zealand venues.  New Zealand hosted the championship twice— Christchurch (1906) and Hastings (1912).  The geographical remoteness of both the countries (Australia and New Zealand) made it difficult for foreign players to enter the tournament.  In Christchurch in 1906, of a small field of 10 players, only two Australians attended, and the tournament was won by a New Zealander (Tony Wilding).  Lawn Tennis Association of Australasia was one of the twelve national associations of tennis which established the International Lawn Tennis Federation (ILTF) in a conference in Paris, France on 1 March 1913.  From 1905 until 1919, New Zealand and Australian tennis players participated in the International Lawn Tennis Challenge (Davis Cup) under the alias of "Team Australasia", the team claimed a title six times (1907, 1908, 1909, 1911, 1914, 1919), however, there were attempts to severance this trans-tasmanian partnership, in order to allow New Zealand players to represent their nation on international tennis events.  In 1922, New Zealand dropped out from this partnership and on 16 March 1923 New Zealand Lawn Tennis Association was granted affiliation to the International Lawn Tennis Association and thereby became eligible to enter the International Lawn Tennis Challenge in its own right.  New Zealand Lawn Tennis Association filed its first challenge with United States Lawn Tennis Association for 1924 International Lawn Tennis Challenge.  Tennis New Zealand was the founding member of Oceania Tennis Federation in 1993. Sania Mirza and Mahesh Bhupathi were the defending champions.  They accepted the invitation for the tournament, but withdrew before their match against Carly Gullickson and Bernard Tomic and were replaced by Akgul Amanmuradova and Rik de Voest. Chuang Chia-jung and Hsieh Su-wei were the defending champion, but Hsieh chose not to participate that year.  Chuang partnered with Yan Zi, but they lost in the semifinals against Chan Yung-jan and Abigail Spears. Chan Yung-jan and Abigail Spears won in the final 6–3, 6–4 against Carly Gullickson and Nicole Kriz. The 1912 World Hard Court Championships (WHCC) (French: "Championnats du Monde de Tennis sur Terre Battue") was the inaugural edition of the World Hard Court Championships tennis tournament, considered as the precursor to the French Open, and was held on the clay courts of the Stade Français at the Parc de Saint-Cloud in Paris from 1 June through 9 June 1912.  This tournament was open to all international amateur tennis players and was part of a series of world championships being advanced by the International Lawn Tennis Federation (ILTF), the others being the World Grass Court Championships (Wimbledon) and the World Covered Court Championships held in a variety of countries.  The WHCC was open to all nationalities unlike the French Championships which were open only to tennis players who were licensed in France. Carly Gullickson (born November 26, 1986) is a former American professional tennis player. Carly Gullickson and Travis Parrott were the defending champions, but lost in the first round to Gisela Dulko and Pablo Cuevas 2–6, 4–6.
