Question: Who owns the retired Grand National-winning National Hunt racehorse trained by Donald McCain, Jr. in a civil parish north east of Malpas and west of Nantwich?
Context: Flyingbolt (1959 - 1983) was a famous racehorse.  Officially he is the second best National Hunt racehorse of all time, after Arkle.  A comparison of their merits is probably best illustrated by the Official Steeplechase Handicapper, who at the end of the 1965-1966 season rated Arkle the superior by only 1 lb (0.5 kg). " Timeform", the highly respected racing publication, had a difference of 2 lbs between them.  As a hurdler, Flyingbolt was the best Tom Dreaper ever trained.  His wins included the Gloucestershire Hurdle at Cheltenham (now the Supreme Novices' Hurdle) and the Scalp Hurdle at Leopardstown (now the Irish Champion Hurdle).  He also finished third in the Champion Hurdle at Cheltenham.  Flyingbolt and Arkle never raced against one another, mainly because they were trained by the same man and he preferred to keep them apart.

Iris's Gift was a National Hunt racehorse trained in Britain by Jonjo O'Neill. Puntal (foaled 1996) is a National Hunt racehorse who won the Betfred Gold Cup in 2004 and ran in five consecutive Grand Nationals from 2003 to 2007 with limited success.  He was formally trained in France before moving to Martin Pipe in 2002.  Puntal is now trained by Martin's son David Pipe. Kicking King is a National Hunt racehorse trained in Straffan, Co.  Kildare, Ireland, by Tom Taaffe.  He is best known for his victory in the 2005 Cheltenham Gold Cup, the major Chase run at the Cheltenham Festival.  He also won the King George VI Chase in 2004 and 2005: once at Kempton and once at Sandown Park, when the race was relocated due to the development of an all-weather track at Kempton.  His Boxing Day win on Sunday 26 December was a first; when See More Business won the race in 1999, Christmas Sunday was still observed, so that year the race was first-scheduled for the Monday.  Thus he was the first horse to win twice on non-weekdays.  He was second twice in previous Cheltenham Festivals, in the 2003 Supreme Novices' Hurdle, and in the 2004 Arkle Challenge Trophy.
