Checking historical information in the Medical Register The Medical Register was published in book form between 1859 and 2004. We have worked in partnership with genealogy company ancestry.co.uk to make the majority of this information available online. ancestry.co.uk has digitised every fourth register from 1859 to 1959. These are fully searchable and you can also view original register entries online. Please visit their website at http://www.ancestry.co.uk for further information. If you wish to consult an original copy of the Register, most large public libraries hold copies of it. Alternatively you can contact one of the UK and Irish copyright libraries (pdf).
