According to Ompal Singh Tugania's book based on the records of Bhats which is a community of bards and genealogists in North India, Dhaka's are one of few Jat clans having origin from Chauhans.According to Dr Naval Viyogi In a period of third century AD many hoards of Taka coins have been recovered from Nagpur region, which were introduced by the Taka Nagas of North-West. Linguists have informed that these Taka people reached and ruled in the region of Dhaka of Bangla Desh, since the word ' Dhaka' is a linguistic (Pali) variation of Taka. In the second act of Sanskrit play mrcchakatika a dialect has been used by author, known as Takki. Taki, Takka or Dhakka is the Prakrit dialect which has been called by Pischal language of East Bengal spoken around Dhaka, but there is another interpretation too, since word 'Ta' has been changed to 'Dha' due to the tendency of change from Sanskrit to Pali or Prakrit as cited above, hence the original word is Taka from which Dhaka has been derived.
Dhikauli village near Baghpat and Gurdaspur village in District Bijnor of Uttar Pradesh also has a Dhaka family.
