I'm still researching this family and came across info about the builder of St. Michael's Parish Church. This is noteworthy because this Sisley lived in that parish. I noticed that the surname of the family in the are wasn't Collomore or Collmore as common seen but Collymore.

Captain Robert Collymore, the builder of Saint Michael's parish church in 1665
This is a fascinating story about Amaryllis Collymore:
https://www.ucl.ac.uk/lbs/person/view/2146639537
She was sold to her white lover and that's how she became known by that surname. They had as estimated 11 children who were enslaved.
Amaryllis gained her freedom and it says she was "the richest free woman of color in pre-emancipation Barbados"
Doubtless, there were other enslaved people who took the Collymore surname.
And the reason I bring this up that Sisley is my son's direct ancestor and he just recently got DNA test results show him as 13% Caribe (indigenous people of various groups in the Caribbean / West Indies). There aren't a lot of options in our tree for where this DNA could have come from, and Sisley is definitely the most likely ancestor to have had this lineage.
This far back and if she had actually been one of the enslaved or freed Collymore family, I don't know if I can find records from there to reflect that, but I do know that no one has been able to prove who her parents are and it's only stated that she's 'possibly' a descendant of the Thomas Collmore / Cullamore connected to her here.
I joined a Taino DNA and genealogy research group and was provided with a long list of DNA kit numbers from the remains of deceased Taino people as well as some living folks whose kits were used in a 2018 study on Taino DNA. My son matches these folks, even showing estimated MCRAs with them and when I use the Gedmatch chromosome paint tool with them, he shares Amerindian DNA with them.
This would explain the puzzling 20-20.8% Iberian DNA my son's previous results have shown also.
I can't prove this Sisley was from the indigenous Collymore family, not yet anyway, but the DNA and the fact that it was a Collymore who built the church in her parish seem to point to that.
I don't know how much additional information I might come across over time, but I'll share whatever info I find in hopes it will provide more answers about this Sisley's lineage. I'm hoping maybe someone in the Taino DNA and Genealogy group might have info actually from that area on the Collymore and Bohannon families.
