Lt. Col Mathew Daniel has written about his own family and people. They were ( were but not are ) people linked to (born there, or had parents born there) Bolghatty.
These days, Meenakshi Reddy Madhavan, daughter of N S Madhavan is famous for her bloggings. This gentleman, Madhvan from the Indian Administrative Service ( IAS) has written a book based on the history of Bolghatty. Refers to gentlemen engaged in ship building. Did he know about the story of Portugese sailor who married a nair woman, sired children who later day carried title and surname like Veliath (nair) Ausuez ( Portuguese ) like a double barrel surname.
The family branch of Lt. Col. Mathew Danel Veliath, is said to have, dropped the assuez idenity and retained the Veliath part, when sarong worn by Anglo Indians because expensive. This story could be joke, because, the Current day Veliaths were land lords and affluent.
There are few families with the name Assuez and some with only Veliath.
The Asuez families are Anglo Indians the Veliaths are simply Latin Catholics. (they all go to the same church any way)
The Veliaths are mostly migrated and gone to far awaylands of the US and UK.
Col Mathew Veliath himself lives in Maradu.
