You have a beautiful gun. If you got a good deal it was more likely due to barrel length than name. Churchill's are in a down market, but grouse hunters love them. Gorosabel is not obscure. People tend to only recognize the handful of makers still in business. Pedro imported into the eighties and made some fine guns. You will have to check the date, but from the looks of it, I imagine Diego Godoy was shop supervisor, a man still known for putting best guns right. Go to the Spanish forum on Shotgun World and you will find five pages of posts regarding proud owners of Gorosabels.
