We wish to establish which Coad lines are related by blood and whether the family reconstruction in the Coad-Coode one-name study is accurate.

In doing so we 

* Find any mistaken connections in family trees

* Discover information which may solve research problems, and/or resolve brick walls

* Sort out multiple families found in the same location

* Confirm or get clues regarding migrations

* Confirm suspected events, such as illegitimacy and adoption

* Validate family history research

* Bridge gaps in the paper records

* Combine results with research in early records to determine the number of points of origin for the surname

* Preserve DNA results for future research, to protect against any male line becoming extinct
