Hi there ! And welcome to the Kintyre Forum.
This is a late reply !
Perhaps her name was Ann Campbell b1716 in Auchinbreck, Ayrshire.
I found this source on Ancestry and they are down as having another two children... Roger 1740 born in Campbeltown and died in Cumberland NC in 1789. (lots of certificates available to see) Also, Henry, born and died in Cumberland, NC. 1755-1799.
..., Iain.
