https://en.wikipedia.org/wiki/Oera_Linda_Book"The Oera Linda Book is a manuscript written in a form of Old Frisian, purporting to cover historical, mythological, and religious themes of remote antiquity, from 2194 BCE to 803 CE. Among academics in Germanic philology, the document is widely considered to be a hoax or forgery."
Although just because Wikipedia says it's so, doesn't make it so.
Having said that the Dead Sea scrolls tell us that Abraham would have been a white man.
In a round about way.
Sarah, the wife of Abraham (Father of all Hebrews)
Her skin was pure white; ‘She had long lovely hair; Her limbs were smooth and rounded (her thighs were shapely) ‘She had slender legs and small feet; ‘Her hands were slim and long and so were her fingers.’
-- Description of Abraham's wife Sarah in the seventh Dead Sea scroll
....and beautiful is her face! How...fine are the hairs of her head! How lovely are her eyes! How desirable her nose and all the radiance of her countenance...
How fair are her breasts and how beautiful all her whiteness!

Sarha was his kindred. Probably his sister. Gen 20:2
