I did a search and found these words:
Contrary to popular belief, there is no central register of name changes in the United Kingdom. Deed Polls are not registered anywhere unless they are "enrolled" i.e. lodged for safe keeping, in the Close
Rolls of the Chancery (from 1851 to 1902) and from 1903, in the Enrolment
Books of the Supreme
Court of Judicature, which is located within the
Royal Courts of
Justice in the
Strand,
London.
Enrolling a
Deed Poll provides a public record of a person's name change and since 1914 the details of the name change are published in either the
London or Belfast Gazette [What is the
London Gazette]. Alarmingly, the person's name change details and home address are also published on the
London Gazette's website for all to see. Fortunately, it is not a requirement to enrol a
Deed Poll. Furthermore, because enrolling significantly adds to the cost and the time taken to change a person's name and because most people who change their name only wish to inform those who have a reason to know, only one in every two hundred
Deed Polls is enrolled. All other
Deed Polls are unenrolled, which is the type we issue.
Deed Polls that have been enrolled at the
Royal Courts of
Justice in
London remain there for about five years. After which (and going back to 1851), they can be found at the National Archives, which is located at
Kew in
Richmond,
Surrey.
Looks like you are probably not going to find what you want.
