Joshua H Caton was born in Moberly, Randolph County, MO
I only know that he and his wife and older children traveled from MO to CA.
before my grandfather was born James Lewis Caton-( twin of Mary Luella Caton
who only lived a few months).
The other clue I have is that his father, Noah Simon died and was buried in
St. Clair County, MO.
I'm still researching for details.
Hope that helps
