In the 1850 Manchester, Ontario County census we find
John Patton 56 born PA
Lydia Patton 50 born NJ
James C Patton 25 born NY and wife Velina 21 born NY
Hugh Patton 21 born PA

In 1860 John is in Michigan. When did he come to Ontario County and when did he leave? Who is Velina? Did James and Velina marry in Ontario County?
Where was John Patton in 1840?
Any advice or suggestions are welcome.
