Websites like Ancestry.com and Findmypast are your new best friends. They host databases of parish records, census data, and even royal household lists. Use them to track your ancestors back to the 18th or 19th century, then look for connections to landed gentry—often a stepping stone to royalty.
Don’t forget open-access resources. The National Archives in the UK has free guides on tracing aristocratic lineage, while FamilySearch.org offers vast international records. Pro tip: search for “pedigree chart” or “peerage database” to find pre-compiled trees of noble families.
