That's interesting that you just discovered Sealand Hall on your own. He was born 3 May 1781 in Cheshire, New Haven County, Connecticut, a son of Jonathan Hall and Jerusha Gaylord. Jonathan Hall (1754-1805) is listed in the 1800 census of New Hartford, Litchfield County, Connecticut. I don't think Sealand Hall had Collier ancestors.
I suspect that my ancestor Jonathan Hall, who was born in about 1811 in Chenango County, New York, and died in 1875 in Minnesota, was a son of Sealand Hall and his wife Abigail. Seland Hall is listed in the 1820 census of Guilford, Chenango County, New York.
I'll send a family group record for them to your e-mail address.
