Genetics of the White Widow family

Im trying to figure out what the genetics are for the white widow family of plants. i know a few of them but its hard to get info on a few others.

White widow, Black widow(mr. nice): south indian x brazilian (supposedly, its argued.)
White Rhino: White Widow x Afghan
Snow White: unknown indica x unknown
Misty, Medusa: "Sister of white widow" more indica than ww, unknown x unknown.
Great White Shark: White widow x Super skunk
Chrystal: northen lights x (northern lights x white widow)
White Castle: White widow x Ice (one of my favorties)


ANYONE HAVE INFO ON SNOW WHITE OR MEDUSA/MISTY????

snow white seems awfully similar to white rhino but its different somehow. misty has to be similar to both of them as well... they all are indica heavy widow family plants.

Misty by Nirvana is a White Widow x Northern Lights Shiva selection stinky, kinda likean old sock, is the description..500gm per sq. Meter, 8~9 wk. Snow White is another Nirvana plant with genetics as followsWhite Widowx Unnamed USA indica, berry earthy smell 450~500gm per sq. Meter 60~70 days. Hope that helps a little.
