.
My info came from a Univ of Vermont Extension which is a pretty decent article.

The Loganberry was made in the early 1880’s in California by a horticulturist with this name. It resulted from crossing the European red raspberry cultivar ‘Red Antwerp’ with the American blackberry cultivar ‘Aughinburgh’. The conical red fruit wasn’t flavorful, so not popular, but this hybrid was used in further breeding.
Crossing the loganberry with a raspberry in Scotland in 1962 gave us the Tayberry, named after the Tay river there. Its red fruit are larger and sweeter than the Loganberry, and ripens mid-season.
A cross in the 1980’s in Scotland between the tayberry and a hybrid seedling gave us the Tummelberry. Its deep red fruit are conical, late in the season, and retains the core when picked.
Similar to the tayberry is the Wyeberry, only it is more winter hardy and tolerant of fluctuating temperatures, but quite thorny. It looks like a red raspberry, tastes like one with some boysenberry flavor, and has higher yields than many raspberries but fruit may be hard to pick. It was developed at the University of Maryland.
Many have heard of boysenberries, most likely from syrups or jams, and in particular the ones that made Knott’s Berry Farm famous. This fruit was a 3-way cross between the loganberry, a raspberry, and a blackberry. In the 1920’s, a berry farmer named Knott from southern California and the USDA breeder George Darrow (as in the Darrow and Olallie cultivars, among others) visited the former farm in northern California of a man named Boysen. There they found some vines Boysen had bred, hidden among the weeds. Knott took these back to his farm, nurtured and began cultivating them, and in 1932 began selling the popular large and tasty dark berries at his then farm stand, and named them after their original source. You may find plants both with or without thorns.
The wineberry (R. phoenicolasius) was introduced from Asia both as an ornamental, and to breed with raspberries. It has naturalized since then in the wilds in many areas and has become invasive. The Marionberry is actually just the cultivar Marion of blackberry (named for the county where it was tested in Oregon), being a hybrid of two other blackberries. Similarly, the Olallieberry is the cultivar Olallie (from the Chinook name for berry) —a cross of youngberry and loganberry.
