Dear Richard,
Sorry, it took a while to get back to you, but I have been traveling and am just now getting caught up. Rebecca and I both descend from Benjamin Cooke Sweetser, I and I found her while working on my Sweetser lines quite some time ago. But, thank you for bringing her back to my attention. I've added her husband, Warham, and some links on her profile that will help me to do future research. I did a search as to her burial as well, but also came up empty. The only clue is https://www.findagrave.com/memorial/37604268/rebecca-parks which states: "Burial Details Unknown. Specifically: After death of Her husband Gen. Warham Parks, Rebecca (Gorham) Parks returned to Charlestown, Mass with her children and burial location is currently unknown." I found nothing in Charleston/Boston. But, I did find a death notice in The Boston Advocate which I copied onto her About section. My guess is that if you want that info you'll have to go to the location and start digging through actual documents. I'm unlikely to do that being over 3000 miles away.
Sorry, I couldn't be of more help! Please feel free to contact me with any other questions you have.
Sincerely,
Jessica M. German, Geni Curator
P.S. Genealogy is nothing if not a continuous deep dive down a rabbit hole, and I'm currently stuck in a more distant rabbit hole. If I live long enough I'd like to get back to my Sweetser/Gorham lines!
