I haven't found anything on either Henry or William. Hubbard was up in age on the 1820 census so my guess is he died before the 1830 census. There seemed to be confusing trend in the Brewer's from VA & NC with having names passed down or cousins with the same name that were close in age. If they only knew how much chaos they've caused all these years later. A good example is the 2 Isaacs. I have 2 1850 census, 1 for AL & 1 for TN with each of them listed. One was born in VA, the other in GA and they were about the same age. It depends on who you believe when it comes to which one was married to whom or whatever. The only help I can be right now is GOOD LUCK! & ENJOY the hunt.
