So these are F2 seeds which should show most variation also if crossed within themselves.
Simply pick up the phenos you prefer or think resemble mostly the parents and backcross every further plant generation with it. At about F4-5 it would get stable enough to be called a strain, maybe Amnesia Haze if you like
Thing is, since you don't know or have info on original parents, would be impossible to breed with a goal of resembling what you don't know. Instead select for phenos that you find most appealing to your taste.
See, amnesia are mainly two varieties(non auto), one is a SSH cut(or pheno) so it should be 50%haze, 25%skunk and 25%NL, these are the original parents of SSH, then selected to Amnesia.
The other Amnesia is the above Amnesia cut crossed with Nevil's Haze, but yours si most likely derived from the first one.
This Amnesia photo cut was probably crossed to a lowryder and backcrossed several times to the original cut.
Usually breeders work with different phenos from the original plant gene pool, this way next generations don't lose vigour with inbreeding and avoid bottlenecking.
I think both of your phenos(if pollenated with amnesia male) can be called amnesia auto, maybe labled F2 for who wants to know more
