My wife has Mexican blood, brought by the spanish to new mexico. She found that a lot of her spanish ancestry was through conversos (jews that converted to catholicism during the inquisition so they wouldn't be killed). Apparently, they had originally came from the middle east and near east regions of asia and settled in Spain. Quite a few left to inhabit the Canary Islands and then the Americas with the conquistadors. This might explain any strange middle eastern results.
