Wiffens Born before 1800

Digging deeper into the 1841 census, 118 of the Wiffens were born before 1800, and of those the majority resided in Essex, Kent, Suffolk, and Norfolk.
Due to the number of older people alive in 1841 who are residents of Suffolk and Norfolk, the significance of these counties is greater than their percentage of the Wiffen population.
The preponderance of early records originates along the east coast of England, stretching from Suffolk down to Kent. The locus of Wiffen records in Essex before 1650 is a cluster of parishes in the North Border Parishes of Essex between River Stour and River Colne. Unfortunately, we lack enough data points to establish migration patterns between Kent and East Anglia, or between Kent and Dorset. Perhaps shipping and sea travel connects them.
