Boydens of Guilford VT

There were 4 Boydens in Guilford VT in the 1790 census: James and Daniel, sons of Daniel and Mehitabel Mann, and Daniel Jr.,who married Tabitha Goodenough. His father Daniel married Rebecca Barber and James married Susannah Norton. However I can find no info on the 4th Boyden, namely Joseph.Is he related to the others? thanks for any help, Helga Andrews
