Harkor is Kuldevi of Lohana clan. She is worshiped by Lohanas along with his brother Rana Jashraj.
As per their folk tales, Jashraj, who lived around between 1205 and 1231 near Lohar-gadha ( present day Lahore ), was at his wedding mandapa when he came to know that enemies were taking away cows, an animal holy to Hindus. Hearing this he left his wedding and went after enemies with a group of warriors to save cows. He was assisted in war, by his own sister Harkor Pobaru, who led a group of Lohana women warriors. Although, the enemy from Kabul was eventually defeated, and Jashraj became victorious, he was killed as a result of an enemy strategem. Harkor also fell in the battleground as martyr. Ever since both are being worshiped by Lohanas and Bhanushalis as worshiped as kuladevata and kuladevi, respectively.
She is especially revered and worshiped as clan-deity by Pobaru branch of Lohanas, in which she was married.
