Following paths here on Geni, it appears Elizabeth (Tilley) Howland, "Mayflower" Passenger descends from English Royalty. An example would be as follows:
Elizabeth (Tilley) Howland, "Mayflower" Passenger is Henry I "Beauclerc", King of England's 15th great granddaughter.
Henry I "Beauclerc", King of England → Empress Matilda (his daughter) → Henry II "Curtmantle", King of England (her son) → John I "Lackland", King of England (his son) → Henry III, king of England (his son) → Edward I "Longshanks", King of England (his son) → Edward II, king of England (his son) → Edward III, king of England (his son) → John of Gaunt, 1st Duke of Lancaster, 1st Earl of Richmond (his son) → John Beaufort, 1st Earl of Somerset (his son) → Edmund Beaufort, 2nd Duke of Somerset (his son) → Lady Anne aka Jane Beaufort Beaufort (his daughter) → Elizabeth Saville (her daughter) → Isabel Ayshton Marshe (her daughter) → Robert Marshe (her son) → Rose Rushe (his daughter) → Joan (Hurst) Tilley, "Mayflower" Passenger (her daughter) → Elizabeth (Tilley) Howland, "Mayflower" Passenger (her daughter)
It is my understanding, however, the More children were the only passengers with any known royal descent.

"The More children are the only passengers with known royal ancestry, with descent from King David I and King Edward I of England."
I've been looking through the lines above, and would welcome any thoughts. There are sources attached which appear to be approved/proper. With Elizabeth being such a famous passenger and historical person, if she did in fact have such ancestry, wouldn't it be curious if it was missed by historical researchers and documented here? I guess stranger things have happened, but also thought we might want to take another look.
Thanks everyone!
