The head of this family is currently unknown. However they are interesting because Charles Sergison (1654-1732) bought Cuckfield Park, Sussex during his time as Commissioner of the Navy and Clerk of Accounts. Although he married he did not have any children so the estate passed down through other members of the family. I would not have been able to include them in a descendant report for Charles so have produced one called the Descendants of Sergisons of Cuckfield.
