Caffey Surname (John Thomas)

I am researching the surname of Caffey. I have traced my roots back to John (Jake) Caffey-possibly John Thomas Caffey, b. abt 1690(Ireland), father of Michael Caffey b. abt 1720 in Belfast and came to the US as a young man.

I would also like to know if we have a coat of arms.

Any help you can give me would be appreciated.

I have some information about a Michael Caffey that came to the US in the early 1700's. I also have some info on coats of arms. However, one coat does not seem correct or appropriate. I can make copies of some of this info and send to an address if you have one. My email is jeraldcaffey@hotmail.com.
