Here is the link to the map: https://www.planetminecraft.com/project/fort-hernandos-village/ Unfortunately, the link doesn't work to download it, because MediaFire made an absolutely stupid decision of taking down old accounts. If this is the map, we should start asking around the forum if anyone still has it, or try and get in contact with the person who built it.
Have you talked to your brother about this? Maybe you can see if he could give you some clues, that way I might have a better shot at solving this mystery :D
