Hi!
Sorry it took me so long to answer. The Inda surname seems to have originated in the Basque area of Spain or Portugal somewhere back in the 1600 or 1700's. Most of the branches of the Inda family that settled in the USA have been found to have lived within 50 miles or so of each other (if we go back to the oldest ancestor known so far).
It's interesting, there is even an Inda Family Crest!
