I am a financially comfortable miller in a new Massachusetts settlement in the 1650s. How likely is it that I owned slaves? How likely is it that those slaves are local indigenous people vs. people imported from the Caribbean?

I was digging around and discovered one of my ancestors was a reasonably well off miller living in Woburn, MA in the 1630s to 1750s. The family arrived in time for the Pequot War, and was involved in King Philip's War. Both ended with many Pequots, Narragansetts, and Wampanoags sold into slavery. How likely is it that my ancestors would have owned slaves, and that these people were from a local group vs. people brought in from the Caribbean?

Are there resources to find out specifically if they did or did not own slaves? I'm thinking wills and probate, or if I'm lucky, somebody got sued. What other resources are there?
