Hi Charles,
Have you explored the possibility that Hiram descended from Thomas Husted Sr. of New Canaan Parish, CT (formerly Norwalk, CT)?
If that is the line it would be from Robert Husted Sr. as follows:
Robert Sr.
Angell Sr.
Angell Jr.
Jonathan
Peter
Thaddeus
Thomas Sr.
Thomas Husted Sr. had a son named Hiram. Thomas had business in Manhattan and lived in New Canaan. He had large land holdings. He was a prominent Wig politician, Post Master, and business owner, as well as land developer in New Canaan. I think his business in NY had to do with shoe manufacturing.
Good luck,
George Husted
