"Daniel2 Gates … married Rebecca3 Dutton, …daughter of Joseph2 (Thomas1) Dutton and his wife, Rebecca Merriam."
Even though they were not included in the Hale Collection, it is not impossible that Daniel and Rebecca were buried at the Old Cove Burying Ground. However, since he was deacon of the church at Millington, burial in that part of the Town of East Haddam seems more likely.
