Abraham was of Andite blood. As the Urantia Papers tell us:
I shall show in the following papers these Andites (and Abraham) were of a reddish, or ruddy, skin color. We also know they were of a roving disposition from the historic record of the family of Abraham on the move from deep in Mesopotamia to Canaan. Furthermore, while they were close family in-breeders (Abraham and Sarah were half-siblings) they followed an impulse to share their blood lines with non-Andite stocks. This impulsive biological behavior may be found on my web site under the title THE MYSTERIOUS HABIRU, http://www.world-destiny.org/a29hab.htm.

Curiously, Victor Mair made the discovery of Andite mummified descendents from the Sinkiang (Xinjiang) region of China in 1994. They were taller than the Chinese, looked like western man, were reddish colored, and wore Celtic Tartan clothing. See The Tarim Mummies, J. P. Mallory and Victor H. Mair, Thames and Hudson, London, 2000.

According to Bishop Ussher’s 17th century chronology, based on Genesis entries, Abram (Abraham) lived from about 1996 BC to 1821 BC, 175 years. More recent studies put it at 2053 BC to 1878 BC. http://bibletimeline.net/biblehistoryblog/biblical-timeline-abraham/#sthash.MdG71mrP.dpuf

As Jews and Christians well know Abraham bore two names: Abram and Abraham. According to the Bible story he was 99 years old when his name was changed. Yahweh, El Shaddai, spoke directly with Abraham to produce this shift. Gen 17:4 "my covenant is with you, and you shall be the father of a multitude of nations."

We can question whether it was Michael who spoke with Abraham or if it may have been Melchizedek standing in for Yahweh. In Gen 14:18-19 we are told that "Melchizedek king of Salem brought out bread and wine. He was priest of God Most High, 19 and he blessed Abram.

The first name, Abram, is easy. It is composed of Ab and ram. Ab is the Hebrew name for father. ram means high, or lofty, or exalted.

But when we encounter Abraham we run into a seriously difficult problem. The first part, Ab, we know = father. The second part, raham, has given untold trouble to biblical scholars. Everybody and his brother has speculated about the origin since it has no known etymology. This speculation has been going on for centuries. For example we find remarks like:

This ruminating about the origin of Abraham's name led to the following amusing remark, which I reproduce in full here:
