When checking Wikipedia about Caven, this is what I found.

As you can see by the modern map, County Caven is a border county, south of Ulster. It is still predominantly Catholic.

There are 2 Claremores in this largest county of Northern Ireland, so I don't know which one she came from. But the marriage took place in George's home town of Caven, probably in 1683. I only know of the one son who came to America, Francis who was born in 1715. But Ancestry has lots of interesting possibilities. It suggests she married Arthur Beatty, and had parents (with 2 different mothers named) and a lot of other children.
Caven is where the Beatty family lived, and Martha Cairnes Beatty died in April of 1743.
I'm sticking with one simple story at this time. I'm always willing to admit mistakes, and change my story later.
