Are they Indians?

We have a church up the road at Stoke Dry, which is loaded with legends.
They say that some Gunpowder Plotting was done in the tiny room above the porch by Sir Everard Digby (who was hung for treason in 1606) , also that witches were left up there to starve to death. There is no evidence of this, and the plotting is in doubt.

But there are some very old murals still in evidence on the walls. Cromwell's troops of puritans didn't manage to scrub all these out.
The strangest of them are of a King or Saint being killed (with a gentle little twist of his lips)by figures with bows and arrows, dressed a bit like native Americans. These were drawn centuries before Columbus, we have no idea where the artist got the idea.*

I was returning from the reservoir where I had got a photo of a swan grooming at the water's edge, when I nipped into the church. I found about six more subjects. The strange thing with life and blip. Nothing yesterday and then about 10 shots today.
This is not the best 'Picture' but I think is the most fascinating.

* New Info from the net re this figure:

Eventually Edmund ( Matyred King of East Anglia) was taken prisoner, whipped and tied to a tree and shot with arrows 'until he bristled with them like a hedgehog or thistle'. He was then beheaded and the head thrown into bramble thickets in Hegelisdun Wood. The date was given as November 20th which remains St Edmunds' Feast Day today. The survivors searched for the head and found it guarded by a wolf and calling 'here, here, here'.
