High Quality Content by WIKIPEDIA articles! Dulay (pronounced doo-leh) (also Dulai or Duley) is one of the many last names of early Jatt tribes that played an important historical role in Sikh history. Dulay is a clan of the Jat people originating from the Punjab state of India. Dulay is spelled as Dula in alibata, the pre-historic Filipino native alphabet, which explains the fact that the Dulay from England became Dula in the Philippines during the pre-Hispanic time and Duleh in India. This also explains why the ancient Tagalog dialect has several Jatt-Hindu words because of several exchanges of communications between the Dula/Dulay of the Kingdom of Manila and Duleh of the Jatt people of India.
