Question about ancestry and special samples

[Rafael Passoni]

Is there any company that provide autosomal ancestry report from special samples?
I have dentures from both my paternal grandparents, old blood on cloth from my maternal grandmother and a used razor from my maternal grandfather.
I read it on an article:
"LivingDNA used DNA collected from a postage stamp to help a woman found as a baby in a blackberry bush to locate her family. "
