Norfolk
There is a lot of activity in the King's Lynn area, with Causton mutating to Coston and probably Cason. The tree headed by John Cawston about 1450 starts in Essex but arrives in Norfolk by 1500. It is likely that all the trees mentioning Felbrigg join up somewhere. This research is bedeviled by a point where two Nicholas Caustons are born in 1695 and 1697, marry and have children. At present the two lines cannot be disentangled. The early years of this tree still have to be confirmed by checking against parish records etc. It includes an early branch that moved to Kent.
