Does anyone know the name of this iris?

I dug it up last year from and old abondaned house. This is the first bloom since I got it.

It is definitely an historic iris, but its hard to see from the angle you took the picture. Can you take a picture not looking down upon it, but rather showing the falls and standards in proportion, like shoot the picture even with the bloom?

Here is a better picture

another

Can you ID this one?

The variegata looks like ACCENT.
What do you think?
Don;'t know what the purple one is. Maybe one of the Sambucina type iris.
