[2] Many members of the Soomro tribe were among the first in Sindh to convert to Islam from Hinduism but initially continued to maintain several Hindu customs and traditions.

[13] Ghulam Hussain and others argue that the Soomros and other native tribes indigenous to Sindh slowly began to 'Ashrafize' themselves by remaking their genealogies to further associate themselves with Syeds whom they possibly intermarried and acquired power through.

He considered Soomras, a hybrid race that was mix of Sindhi-Arab blood, emerged after the Umayyad caliph Sulayman ibn Abd al-Malik’s decree asking Arab officers posted in Sindh to settle in the land permanently.

[3] Hence, Dr. Baloch writes that:Soomras were descendents of these hybrid princes, whose ancestors, according to common legend, were either Arabs or their grand-sons on the mothers’ side.
