What I think you should do...
Do what I did. Three bag seeds could be two females and one male. So you grow them, allow the male to pollinate the female, and collect the seeds.
Now you have some genetic diversity and a decent seed stock of a Sativa-Indica hybrid.
Start 20 to 50 of these seeds, veg for 5 to 6 weeks and filter out the males, resulting in 10 to 25 females. Clone all of these plants, develop a mother room and flowering these plants out. Smoke them and select 2 or 3 phenotype varieties as keepers.
Maintain those 2 or 3 superior mother plants and name them based on their characteristics.
Just growing out some accidentally pollinated bag seed then selling it and calling it anything other than bag seed is bad form. If you want to name it you need to make it.
I named mine Element Zero. This name tells me that this is the start point of all future breeding endeavors. Currently I am searching for a potent Element Zero male to cross with Wappa, Sensi Star, Lemon Skunk, Cole Train, Motavation, Warlock, and one of itself to generate a unique F1 generation of several strains that have a similar characteristic to my starting point. This gives me a bunch of seeds I'll spend the rest of time filtering though while growing other genetics on the side. Cross breeding these and developing stability is the plan.
