That doesn't make sense. Wasn't there a legal requirement for public register so that it could be checked, not checked if you needed to and had the exact spelling of a particular name.
For example, take the property price register, they spelling on there can be brutal, and big mistakes can mean you don't initially spot what has been sold in a particular area, but by broadening your search you find all properties sold.
Eg:
Upper Leeson Street
might be
Up. Leeson St.
or
Leeson St. Upper
Or
Michael Francis Murphy
Mike F. Murphy
