I am sorry I am of no help in your finding a stud with Bonanza Can back to Brother Can bloodlines. My mare was foaled in 1987 and was owned in 1989 by Marinus Stanislaus of Maryville,MO. In 1990 was was owned by Sam and/or Cindy Stephens of Hopkins, MO. In 1993 she was owned by Dewayne or Marilyn Taylor of Diamond,MO. I then bought her in 1995.
Good Luck in your search for a Bonanza Can stud.
