Roberts Bloodline

Thomas Roberts married Joanna Ockenden on 1 Sep 1564 at St Peter's Parish Church, Cowfold in Sussex.

I believe him to be my 10 x great-grandfather.

For all of his descendants (i.e. his children, his children's children, but not their spouses), regardless of their surname, down to the present day, I have mapped where they were born, married or died as far as is known to me.
I am only including those events dated to within one year (or better) and at a defined place in England or Wales (some of the Places are Registration Districts at which events were recorded rather than the actual Place of the event).
Clearly the true number of descendants is much greater than I have found, as should say, an Ann Roberts marry a John Smith it is virtually impossible to identify subsequent generations.

Maps

	This map shows the total count of Births, Marriage and Death events of those descendants by Ancient County, across all years from Thomas and Mary's marriage to the present day. The top counties (most events) are clearly Sussex, Middlesex and Surrey.
	This map shows the same events as above, but demonstrates that they were not evenly spread across the counties, but there were centres of activity. The large number of smaller centres show that although the descendents did distribute themselves widely, none established significant Dynasties outside of the originating counties.
	This only includes Births (marriages and deaths now excluded), to help de-clutter the mapping. Arbitrarily I have chosen the year 1900 - prior to that only 50 Middlesex births were recorded, but another 50 were recorded in the next 20 years. It serves as a useful break-point for a change in the centuries-old ways of life and a transition to population mobility and a move away from predominantly agricultural lifestyles. The centres are Cowfold (188), Lower Beeding (122), Henfield (112), Brighton (83), Horsham (77), Nuthurst (59) and Hurstpierpoint (51). The top 10 centres (excluding Brighton) fall within a 5 mile radius and account for 35% of the known births over the 336 years.
	Births 1901-2018 fall predominantly in the London to Brighton corridor, but migration towards larger towns follows the national trend. Top centres are Brighton (294), Horsham (258), Worthing (197), Cuckfield (148), Croydon (131), Steyning (129) and Reigate (122) - followed by Dartford, Wandsworth and Guildford showing the migration north. Brighton accounts for 9% of the 3200+ births, and Horsham 8%.
