Jamestown Rhode Island Connection

I am looking for anyone in or near the Jamestown location. I have John Thoms, born 1640 in Pembrokeshire, Wales but died in October 8, 1728 in Jamestown, North Kingstown Village, Rhode Island. Looking for cemetery information or census or church information. I have his grandson John being born in 1727 in Jamestown but died in Spet. 25, 1815 in Halifax, Windham, Vermont.
