UK - The Queen & Her Consort

Queen Elizabeth II's patrilineal descent is from the House of Wettin, while her husband Prince Philip is from the House of Oldenburg. The earliest connection between these two houses is when in 1478 Christine, Herzogin von Sachsen (b. 1461) of Wettin married Hans, King of Denmark and Norway (b. 1455) of Oldenburg. Both of them (the queen & the prince) descended from this marriage but the queen has a shorter descent in 14 generations while it's 15 for the Prince.
Below are their descent thru Christine & King Hans.

From Queen Victoria & Prince Albert, they are 3rd cousins the queen being a great-grand daughter of King Edward who is a brother to Princess Alice who is the great grand mother of Prince Philip.

In 9 generations both The Queen and The Prince descends from John William Friso, who is by the words of Wikipedia "John William Friso and his wife are the most recent common ancestors to all currently reigning European monarchs. This is a distinction he has held since 1938, when Franz Joseph II -a descendant of John William Friso, succeeded Franz I - who was not a descendant, as Prince of Liechtenstein".
