Hello,great to hear from you!
I have a little more information since I first posted the message, my tree on Ancestry would be useful for you I'm sure. Off the top of my head I think I have Julia's parents names but not where she was born. The same for John. They are very elusive!
So your wife and I have the same great grandparents, making us second cousins!
James and Mary Ann had a daughter Dora Amy RIRIE who married David Willim REES, my grandparents, their daughter Joyce is my mother.
If you would like to see my tree, send me your email address and I will send an invitation, my email address to reply to this message is email@example.com
Looking forward to hearing where your wife fits in and hoping we can help each other :-)
