Hi Elaine, I had my doubts about your connection to Charles of Inver, Donegal he lived at Munterneese,Inver.Donegal I have corresponded with a Mr Moore born in Donegal but living in USA he told me the last of the Coulters had died the previous year his family were cousins. He said they got the land from King William of Orange for services in the Boyne. I can't find the birth or death record of my Charles, that is how I doubted your link.
Yours Aye Jim McPherson Scotland
