Yes, I am trying to identify the members of the very early Mormon congregation at Andover, Ashtabula County. And you are correct that I am not a Grover descendent. I'm not certain as to how much information I can find, but if there is enough, I might be able to write a short article.
Thanks for the reference to Pioneer & Patriot Families of Bradford County PA 1800-1825. I had consulted that Website earlier for information on the Leonards who moved into Ashtabula County from Springfield, Bradford County. (My 3ggrandfather's first wife who died young was Junietta Leonard and his sister married Leicester Upham Leonard.) I had hoped to shortcut the research process by finding a Grover family researcher. I will pass on to you whatever I find out about Gamaliel Reynolds Grover. You probably would not have had a family tradition if he did not remain a Mormon. Persecution made it very difficult.
