Which couple should I use for The Legacy Challenge?

I like the first names the most, but it would be nice if I would know more about them. Basing my opinion on names may not be right.

I think that I like the names of the first two also.

@GITTE2001 @blazerntq I've been playing them the last few days, but as a joined household and they're elders in that save. :) I was planning on possibly starting over tomorrow anyway once I'm hooked up to the internet on my desktop, update my game, and have all my packs installed. The ones I own anyway. I'm only missing Pets and Ambitions. Those I have to reinstall through Origin if it behaves.

I like the names of the second couple, and I guess they aren't married, so there might be a wedding involved later and that's always nice...
