@Bubba's girl this is what is on Greenpoint Seeds' site, which is where I picked up a pack of DVG's Brandywine a while back. "The breeder fertilized a Pink Champagne (a.k.a. Phantom) female marijuana plant with pollen from a Grandpa’s Breath male. Pink Champagne = Romulan x (Purple Urkle x C-99). Not sure of the validity, just a copy and paste that I hope is helpful.
