For White Widow, try De Sjamaan. Ingemar, the guy who appears to have created it back around 1988 was giving (technically, at least, as the government in the Netherlands wasn't letting them legally sell them) his seeds to De Sjamaan at one time. But "one time" was early 2000s. therefore I have no idea whether this is still the case.
Three people (in the Netherlands) were given Bubblegum plants in 1993 - Adam (TH Seeds), and Simon and Tony, who split not long afterward, with Simon starting Serious Seeds and Tony, Sagarmatha Seeds. Each person, of course, then did their own work. Simon's (Serious Seeds) was said to be the closest to the original, more sativa-leaning, and his only IBL strain.
Bear in mind the fact that most, if not all, Dutch breeders have suffered busts and other misfortunes, so their current genetics may or may not be the same as whatever originals they once had. However, if I were you, I would try those three, and I'd try Serious Seeds' version first.
Fruity Juice is an F₁ cross of Thai and Afghani, done by Ben Dronkers, from genetics that he collected back in the day. I'm not knocking the strain - but it didn't come from Indiana.
