Horace Grover born about 1819 in Vermont

My mother-in-law's sister asked me to help find out if we were related to some Grovers she met a while back.  I'm trying to find the connection between the two Grover lines.  So far I'm back to Horace Grover and his lovely wife Betsey Gallop.  No connection yet but I'm having fun so I'll keep going.  The thing is, if I can't find a connection I end up with all this research I'm not sure what to do with.  I want to find someone in that family who is interested and give it all to them.  That will be the next research problem after I work on this.
