have used as my sources the 1569
because they both include the names of all males living
in Cornwall, Devon and Somerset at those times. The Muster
were all men above the age of sixteen who were liable to
serve in the militia and provide arms. The Protestation
recorded all adult male subjects who were required to swear
an oath of allegiance to the crown. There was also a John
who was the progenitor of the Wiltshire branch of Yeos.
He was probably the son of Thomas and Mary Beche, grandson
of William and Ellen Grenville. He purchased land in Great
Somerford in the late 1500s. London has a few strays,
but they can all be traced back to Devon.
main family seat of the Yeo
family from 1350 1582 was Heanton
Satchville in the parish of Petrockstowe
(see blue dot) and most of the Yeos recorded in the 1569
can be tracked back to William and Ellen Grenville or Williams
elder brother Richard (Yea/Yewe). The high density of the
name appears mainly in North Devon/North Cornwall, the parishes
on the south coast were odd Yeos who were probably mariners.
