Royal Genealogy and Family Trees

Queen Elizabeth II and Prince Philip both descended from Queen Victoria and various European royal houses. By tracing multiple generations, genealogists identified several common ancestors that made them third cousins.

Family trees of the British monarchy often include intermarriage among German, Danish, Greek, and Russian dynasties. These historical unions increased the likelihood of relatives marrying across different royal lines, reinforcing political alliances and shared heritage.

Historically, royal families encouraged marriages between relatives to preserve wealth, territory, and political influence. Over time, laws and social norms shifted, leading to stricter regulations on consanguinity in many jurisdictions.

In the United Kingdom, marriage between close relatives is generally permitted under civil law, though the Church of England has specific guidelines. The Royal Marriage Act 1772 previously required consent for descendants of King George II, but it was largely repealed in 2015, affecting how future royal weddings are authorized.
