It seems that the kata was most likely spread into the Shito Ryu and other lineages via Sokon Matsumura (1809-circa 1902). In particular, historical records indicate that he learned it from a Chinese sailor who may have been shipwrecked on Okinawa. However, it has been pointed out that this Chinese man, referred to as Chinto or Anan (both names being associated with two different kata, of course), probably taught a small number of other karate masters around 1800, and that the spread of karate in Okinawa may indeed be through more than one Matsumura.
