Even so, Dhaliwal's primary motivation was the ability to live his faith, said his friend Manpreet Kaur Singh, an attorney and Sikh Coalition board member who is not related to Simran Jeet Singh. Sikh men often take Singh as a last name, while women take the last name Kaur, rather than using surnames that would identify them by caste. Manpreet Kaur Singh has both her mother's and father's last names.
