Out of those early litters came Blackie, an all black Burmese-like male and Daddy Warbucks, a seal point with white feet. Daddy Warbucks sired the founding bi-color female Fugianna, and Blackie sired Buckwheat, a dark brown/black Burmese-like female. Both Fugianna and Buckwheat were daughters of Josephine. All Ragdolls are descended from Baker’s cats through matings of Daddy Warbucks to Fugianna and Buckwheat.
Baker, in an unusual move, spurned traditional cat breeding associations. She trademarked the name "Ragdoll," set up her own registry—International Ragdoll Cat Association (IRCA)—and enforced stringent standards on anyone who wanted to breed or sell cats under that name. The Ragdolls were also not allowed to be registered in other breed associations. In 1975, a group led by Denny Dayton broke rank with IRCA with the aim of gaining mainstream recognition for the Ragdoll. This group eventually developed the Ragdoll standard currently accepted by major cat registries.
Since the spread of the Ragdoll breed in America during the early 1960s a breeding pair of Ragdolls was exported to the UK. This was followed by eight more cats to fully establish the breed in the UK, where it is recognised by the Governing Council of the Cat Fancy. In 1994, a second group decided to leave the IRCA and form their own group due to increasingly strict breeding restrictions. This group later established the Ragamuffin breed. Because Baker owned the rights to the name "Ragdoll", no offshoot groups could call their cats Ragdolls until the trademark on "Ragdoll" was not renewed in 2005.
