Hi! Either someone has fixed it already or you took a wrong turn somewhere. I just reviewed the line* & found the following:
Randolph-94 -> Randolph-13 -> Lane-347 -> Vincent-118 -> Tanfield-2 ->
Tanfield-3 -> Tanfield-4 -> Tanfield-5 -> Brooke-68 -> Brooke-41 -> Braybrooke-2 -> Pole-102 -> Cobham-18 ->
Cobham-19 ->Beauchamp-151 -> Beauchamp-61 -> Vivonne-1 -> Vivonne-2 -> Malet-15 -> Malet-18 (Magna Carta Surety Baron)
* You can't do WikiTree relationship to find the trail, you need to start with the Gateway (Randolph-94), open profiles for his parents, & repeat with the one that has the Magna Carta badge.
