Logic puzzles tend to be popular

Check me for multiple solutions, unnecessary clues, and the like. Edits made based on comments. Please note the new clues 2 and 8.

Six friends (Morgan, Lee, River, Pat, Sam, and Chris) are lining up for a photo. Three of them are in the front row and three are in the back. Who stands where?

1. There are three men and three women. Each row contains at least one person of each gender.
2. Chris, being the tallest, got stuck in the back, on the left side.
3. Two of the women have red hair, one of those two is in the front row.
4. No two people with the same hair color are next to each other in their row.
5. Lee and River, being an overly affectionate heterosexual couple, stand together.
6. River has dark hair. Sam and Pat are blond.
7. The blond woman is jealous of Chris’s dark hair.
8. Pat is standing in front of River.

hmm.

Perhaps I am missing something, but I get two solutions that I'm ok with.

Morgan is a redheaded lady.
Lee is a redheaded lady.
River is a brunette man.
Chris is a brunette man.
Pat is blond.
Sam is blond.

Both of the following arrangements seem to satisfy the conditions, because we know that with Pat and Sam (the blonds), one must be a man and the other must be a woman.

Same as above--of course, only one answer if I take "stands next to" as "stands in the same row," as long as I don't care about order within row.

Order is important, and should only have one solution now, if I set this up right.
