My husband's mother wa a Sherouse we have found at least 17 different spellings of this name.
Anyway one of the second cousins who has researched Johanne Schearus all the way back to Germany where it is found Martin Schearus was the father of the famous Johann.( father of all the Ga and Fl Sherouse/Sherrouse), who was really from Germany.I understand it means outer building like a shed, where they may have done shearing, but not always. I will get in touch with this cousin as they do not use lists for thei research and have disproven some of the myths on this name .
