A deed poll is a legal contract involving only one party. Changes of name by deed poll were (and are) made before a solicitor who issues the document to the person changing their name. The solicitor may keep a copy on file, but it is unlikely to be a certified copy, and the file is unlikely to be kept for more than five years.
There are a number of reasons someone may decide to change their name, including religious reasons, a political statement, disliking the current name, a husband taking his wife's name upon marriage, couples combining or hyphenating surnames to form a new one, and a variety of other reasons.
