On the Relationship

The royal cousinhood rests on the shared descent from Edward IV: Mary, Queen of Scots through Elizabeth of York → Margaret Tudor → James V, the family through Arthur Plantagenet. The “3rd cousin, 14 times removed” figure is the FamilySearch relationship-walk label, carried verbatim (Rule #87).

Sourcing confirmed

VERIFIED on the documented anchors: King Edward IV (GHFH-FRN, 18 FamilySearch sources), Arthur Plantagenet (LCRV-19T, 14 sources), and the Westcott → Perry line that follows, all enumerated on the Plantagenet Descent page. Two Devon intermediate generations (Monck, Arscote) and the cousin-side Tudor–Stuart generations (Elizabeth of York, Margaret Tudor, James V) are marked Research-in-Progress, with no PIDs invented; the Tudor–Stuart succession itself is standard history. The “3rd cousin, 14 times removed” label follows the FamilySearch relationship walk; see the Plantagenet Descent acknowledgments for the chain’s honest caveats.
