I too have been looking for any information I can find on Aaron Houghton Conover and any descendants for quite a while (I am a descendant of Abram Golden Conover, Aaron's younger brother).
I have also found the date you listed for Aaron's death, but if the location was a city called Challis, I believe it was Challis, Idaho (located around mid-state Idaho), not Nevada.Also, I believe that Aaron is John Bonfield's great-great uncle, not grandfather. Zerelda was Aaron's younger sister, and their father was Peter Wilson Conover. Also, Wilson Armstrong was Zerelda's son, not her husband (her husband was Benjamin Armstrong).
For a number of years I have been compiling genealogical data on the descendants of Peter Wilson Conover (I'm not sure why, just an obsession I guess). So far I have found over 2,000 descendants through family and online sources. However, even though Aaron Houghton Conover was the eldest son of Peter Wilson Conover, finding any information on his descendants has always been a bottleneck. I have found some records indicating 4 children, Miles, Emeline, Martha, and Aaron Jr. But all the records stop there, and I've been unable to find anything beyond that. If anyone has further information on their descendants, I would very much appreciate your sharing that information.
Of course, I would be happy to share any data that I have with anyone who is interested.
