Phal Sogo Twinkle = Phal Be Tris x Phal Sogo Tris
Phal Be Tris = Phal Be Glad x Phal equestris
I found out that Phal Sogo Tris 'Sweetheart' = Be Tris x Rudolh
Phal Be Glad = Phal Swiss Miss x Phal Cassandra
P. Swiss Miss = P. Mildred Karleen x P. equestris
Phal. Mildred Karleen = Phal. Judy Karleen x Phal. Sharon Karleen
The hybrid between Phal. equestris and Phal. stuartiana was registered as Phal. Cassandra
It's even confusing for me to follow
Here is a whole page on Phal Cassandra -
