Haran in Fausset's Bible Dictionary

HARAN was Terah's firstborn son, oldest brother of Abram (who is named first in Genesis 11:27, because heir of the promises), father of Lot, and Milcah who married her uncle Nahor, and Iscah or Sarai who married her uncle Abram, being "daughter (i.e. granddaughter) of his father not of his mother" (Genesis 20:12). That Haran was oldest brother appears from his brothers marrying his daughters, Sarai being only ten years younger than Abram (Genesis 17:17). Haran died in Ur, his native place, before his father. In the Hebrew the country Haran begins with 'ch', the man Haran with 'h', as also the Haran the Gershonite Levite under David of Shimei's family (1 Chronicles 23:9). Hara begins with 'h'; Caleb's son by Ephah (1 Chronicles 2:46) begins with 'ch'. Jewish tradition makes Haran to have been cast into Nimrod's furnace for wavering during Abram's fiery trial.
