Hi Jay,
I also posted to you on genforum. I have a connection by marriage to Fred and Grace Heacox, linked through Farmington, CT. I have some info, but it has been very hard to verify their connection to any other Heacox family in the area. There is another Heacox in New Hartford that I think was related but I'm not sure how.
I'd be happy to share what info I have.
