Trying to Reconstruct a Family Sauce

I am typically a salt and pepper guy when it comes to my Q. I am not a fan of layering 45 different flavors on BBQ.

However my grandfather was recalling a sauce from his youth and I would like to try and duplicate it. The sauce was for Chicken and was my Great grandfathers recipe from Georgia.

As my Great grandfather tells it, the sauce was sweet and spicy, but so good that you couldn't stop eating even if your lips and tongue were burning. He used to make it in 2 Gallon batches and cook half chickens over a large pit using an old mattress spring frame. mopping the sauce over the cook.

I have been trying to compile a list of ingredients, but I am not super familiar with Georgia traditions. So far I am sitting with the following and would welcome advice on additional things to try.

Ketchup
Tabasco
Molasses
Honey
Apple Cider vinegar
Peppers (not sure what would work best)
Brown sugar?

My grandfather has had a hard time recalling all of the ingredients and I am not very confident in my list. Welcome the help!

Hmm, didn't realize that I will have to consider adding some to the mix. I know it was a red sauce, but cannot confirm for sure it was ketchup based.

I live on the gulf coast of Texas so I may be coloring it with what I know.
