After reading that the Lothian Health Services Archive held records for the Royal Maternity Hospital, I emailed a request for access to the records of my great, grand aunt who died there shortly after giving birth. This archive is a wonderful resource for anyone who has had ancestors treated at the many hospitals and other medical facilities in the Lothian area.
