I’ve found a new (for me) job or job discription which my translator does not give an explanation for. The word is “ganan” and it is the occupation of many from Jerez during 1886, I have not seen this word in earlier job discriptions. Is anyone familiar with this word or it’s translation from Spanish to English?
