Sorry to tell you but the James you are referring to as son of George and Mercy/Mary Westlake who went to Union Co OH is my gggg grandfather. James was born in 1810 and died in Delaware Co OH in 1896. James was married 3 times. The first time to Phoebe Riley, then to Mary Ann Boyd and the final time to Mary Ann Rose. It is through his daughter Sarah Jane with first wife Phoebe that I descend. I have quite a bit of Westlake family history on the Belmont and Union Co lines...don't find anyone that matches the information you have provided here. If I can be any assistance, please email me at CWmom4@aol.com Happy Hunting to you!!
