There are some posters on FBI's Facebook page complaining about all the storylines Jubal Valentine's son Tyler gets and that his daughter is never shown anymore. I don't remember him ever having a daughter, several others were saying he never did. But someone was sure of it, saying to look it up. I did and there are conflicting results. This article came up near the top.

I was trying to confirm it looking up the Liar's Poker episode they mentioned. Description for it doesn't mention Jubal or his alleged daughter at all. And on the list of guest stars none of the female ones matched.

Inckredible doesn't seem to be a credible site then.

His daughter was on one show. I saw it on a repeat and remember thinking I never knew he had a daughter.
