there is a lot of mixed and contradictory information out there regarding if these varieties are hybrids or not, but I’m pretty sure the vigorous ones I’m growing are hybrids. the information @JeremiahT in post 83 supports this.
Captivator - Often listed as a European American Cross bred in Ottawa in 1935.
Black Velvet - mix of sources, but most describe it as a Ribes uva-crispa × divaricatum cross.
Glendale - frequently listed as a Ribes missouriense x grossularia cross
Pixwell - "‘Pixwell’ was introduced in 1932 by the North Dakota Experiment Station from a gooseberry breeding program started in 1920. It resulted from a cross of Ribes ‘Oregon Champion’ and R. missouriense. Ribes 'Pixwell' - Plant Finder
Tixia - Fully European, Invicta cross with another european cultivar. developed in Switzerland
Amish Red - likely cross. unknown.
Poorman - a cross between Downing and Houghton (both crosses themselves) developed in 1888 in Utah. http://www.chathamapples.com/SmallFruitsNY/Gooseberries.html https://naldc.nal.usda.gov/download/IND43893571/PDF
Hinnomaki Red/Yellow - fully European, developed in Finland. some sources claim the yellow version is a hybrid
Jeanne - Likely hybrid but unknown parentage. Observed for 24 years at the USDA National Germplasm Repository, Corvallis, Oregon. Its origin prior to Corvallis is undocumented.
This is what I have found but if I’m wrong feel free to correct me.
