He gave them a list of targets to look at, which turned up nothing of value.
In 1969 he compiled a list of Florida shipwrecks and mentioned the 3 that I did earlier.
But in 1970, one of those wrecks were found off South Padre Island.

The ship of Farfan (probably its owner)
It sank near Ais, richly ladened with gold and silver, and the Indians of the King of Ais recovered a great deal from the wreck. This wreck is possibly the San Estevan mentioned above, but it could be an entirely different shipwreck. Source: Col. Nay., T. XVI, #1086, f. 359.

So what happened to those 3 ships?
In 1554 three Spanish ships heavily laden with $10 million dollars in silver and gold and 410 passengers ran aground in a stormy sea on Padre Island east of Willacy County.
The remains of San Esteban were found in 1970 and excavated in 1972–73.
