Henry HILLY

I'm looking for any information on Henry HILLY (HILLEY?), born in 1806 in
Hanover, Germany. Henry married Clarianne Thurston in 1837, in Greene County,
Illinois and died in 1895 in Jasper County, Missouri. Henry is buried in
Avilla Cemetery,Avilla, Missouri. Any information would be appreciated.
Also may be someone can tell me what the first steps should be in researching
a name in Hanover, Germany.
