1. Connect Butson branches that pre-date parish registers.
2. Identify uniquely Butson Y-DNA configurations.
3. Add to the Butson One-Name Study information.

Here are some of the pre-parish register questions that may be answered by Y-DNA testing.

1. Did the first Muker, Yorkshire, Butson come from St Agnes, Cornwall?
   
2. Was the first St Agnes Butson a child of the St Merryn-Padstow Butsons?
   
3. Did the first St Merryn Butson come from Blackborough / Kentisbeare in Devon?

A new (2017), secondary, goal for the Cornwall Butsons is to see if any autosomal DNA segments can be identified as Butson DNA segments.
