Willie Nelson was born in Abbott, Texas on April 29, 1933, during the Great Depression, to Myrle Marie (nee Greenhaw) and Ira Doyle Nelson. He was born on April 29, but his birth was recorded by doctor F. D. Sims on April 30. He was named Willie by his cousin Mildred, who also chose Hugh as his middle name, in honor of her recently deceased younger brother. His parents moved from Arkansas in 1929, to look for work.

Willie Nelson has married four times and fathered seven children. His first marriage was to Martha Matthews; it lasted from 1952 to 1962. The couple had three children: Lana, Susie and Willie "Billy" Hugh, Jr. Billy died by suicide in 1991. The marriage was marked by violence, with Matthews assaulting Nelson several times, including one incident when she sewed him up in a bed sheet and then beat him with a broomstick. Nelson's next marriage was to Shirley Collie in 1963. The couple divorced in 1971, after Collie found a bill from the maternity ward of a Houston hospital charged to Nelson and Connie Koepke for the birth of Paula Carlene Nelson. Koepke and Nelson married the same year, then had another daughter, Amy Lee Nelson. Following a divorce in 1988, he married his current wife, Annie D'Angelo, in 1991. They have two sons, Lukas Autry and Jacob Micah. Nelson traces his genealogy to the American Revolutionary War, in which his ancestor John Nelson served as a major.  Nelson owns Luck, Texas, a ranch in Spicewood, Texas, and also lives in Maui, Hawaii with several celebrity neighbors.While swimming in Hawaii in 1981, Nelson's lung collapsed. He was taken to the Maui Memorial Hospital and his scheduled concerts were canceled. Nelson temporarily stopped smoking cigarettes each time his lungs became congested, and resumed when the congestion ended. He was then smoking between two and three packs per day. After suffering from pneumonia several times, he decided to quit either marijuana or tobacco. He chose to quit tobacco. In 2008 he started to smoke marijuana with a carbon-free system to avoid the effects of smoke. In 2004 Nelson underwent surgery for carpal tunnel syndrome, as he had damaged his wrists by continuously playing the guitar. On the recommendation of his doctor, he canceled his scheduled concerts and only wrote songs during his recovery. In 2012 he canceled a fund-raising appearance in the Denver area. He suffered from breathing problems due to high altitude and emphysema and was taken to a local hospital. His publicist Elaine Schock confirmed soon after that Nelson's health was good and that he was heading to his next scheduled concert in Dallas, Texas. After repeated instances of pneumonia and emphysema through the years, Nelson underwent stem-cell therapy in 2015 to improve the state of his lungs.  During his childhood, Nelson grew interested in martial arts. He ordered self-defense manuals on jujitsu and judo that he saw advertised in Batman and Superman comic books. Nelson started to formally practice kung fu after he moved to Nashville, in the 1960s. During the 1980s, Nelson began training in tae kwon do and now holds a second-degree black belt in that discipline. During the 1990s, Nelson started to practice the Korean martial art GongKwon Yusul. In 2014, after twenty years in the discipline, his Grand Master Sam Um presented him with a fifth-degree black belt in a ceremony held in Austin, Texas. A 2014 Tae Kwon Do Times magazine interview revealed that Nelson had developed an unorthodox manner of training during the lengthy periods of time he was on tour. Nelson would conduct his martial arts training on his tour bus "The Honeysuckle Rose" and send videos to his supervising Master for review and critique.Answer this question using a quote from the following article:
