I have a few I've done over the years... I don't know what the family tastes lean towards though. But check over these marinades and see if anything grabs you.
1 cup crystalized ginger
1 cup brown sugar
1 cup water
3 tbs liquid smoke
1 tbs cracked black pepper
Simmer your marinade for at least half an hour before soaking your jerky
1 cup orange juice
1 cup soy
1 cup teriaki
1/2 cup brown sugar
1 tsp cayanne pepper
try those out for something different... if you want more, I have dozens
