It just depends on Education regulations and how far back you go as to whether individuals were illiterate. Accents and dialects were far more pronounced than they are now and I've found spelling anomalies occurred when an ancestor had moved away from home. For instance my Norfolk "Shearing" ancestor moved to Cambridgeshire and to the census enumerator's ear his name sounded like "Sharring" and that's what he wrote down. Meanwhile his uncle had moved from Norfolk to the Midlands and his name was noted as "Shearen".
Other than that, it's often the transcriber of UK records living in foreign lands who mostly mistranscribe names.
