Charlotte, I went to the LDS websites below and found 3 marriages for Valentine Bobb at the first one. The 2 we know in Highland and to Mary Moler in Brown County on 3 June 1850. I would say Leah had passed away since her children were named on her father's will instead of her. Mary (Polly) Moler Bobb may have, too. It doesn't seem he had children with Mary. There is another Valentine Bobb in Logan County, Ohio about the same time. He is born in Germany (Bavaria) also, but his children have different names. Also found death date for Leah as 1850 and Valentine, 10 Sep 1803- 20 Nov 1876. These dates probably submitted to LDS by another researcher, so I can't vouch for them. At the other site I entered Valentine Bobb as the father and found 3 Ohio death certificates. Samuel in 1941, James Marion (they read it as Janner, but the cert says James) in 1928. Both say mother is Lucinda Hatter. The other is Mary Berlin in 1928. Widow of Henry Berlin and daughter of Valentine Bobb and Leah Roads.
