According to * Willson, Richard Eugene. comp. ''The Willson Family 1672-1979'' Ottawa, IL:[s.n.],1979. Print. This edition incorporates 2 previous volumes which are available from Hathi Trust online. The lineage that started in Burlington County, NJ., America with Robert and Ann Willson in 1682, spelled the last name as Willson until children of Jonathan Willson Jr. began recording names spelled as Wilson in 1799. (pg 44) It appears there is a multitude of duplication regarding this. How is this best handled?
