I have relatives on my mother's side of the family who has the surname "Danny". They are of Indian orgin also. The family member with the surname "Danny", that are still living are residing in Guyana and the United States.
Danny is a tough surname to locate, the only member of the Danny family that I know of are the ones that are in my immediate family. I know of my grandfather, who is a Danny, but he is dead and that leaves me without knowledge of his family.
I also know that my grandfather who carries the Danny surname, is also from Portugal or at one time his family came from Portugal, probably carrying the Danny surname. I do know that back then they used to change their surnames or in time the surname might of changed to other versions, like "Dannie."
I'm not sure, but I'm trying to find out more information about the Danny surname as well as other versions of the name.This might not help, but it is good to know that you know someone that is of Indian origin with the surname of Dannie.
