Soloviev is divorced, and has a total of 16 children, 11 from his marriage to his ex-wife, who lives in upstate New York. He also has 5 children from multiple women, who live in the western United States.
He also dropped out of URI. So nice guy, giving that much money to a school he doesn't have a degree from. Net worth of 4.7B with a B.
Apparently, since your post of about 6 weeks ago, he's had 3 more children. His "Wikipedia" entry (I know, they have an accuracy issue) says he has 19 children. So it's been a busy 6 weeks for him. Very prolific! I'll check it again next week to see if he's had any more. (Hahahahahahaha!!)
