McGarrah Family in US

I do have some information on a McGarrah family in the United States, beginning in 1700's, in South Carolina and Georgia. I haven't yet develped all the details I would like to, but am working on it as a continuing project. I have census information, some information about Civil War military service (looks like a group of brothers/cousins all served in the same heavy artillery brigade), one will, and a photograph of my great-grandmother, Sallie Emily McGarrah, born in SUmter Co., GA in 1860.

I am willing to trade information. I have not yet identified the immigrant ancestor(s), but would appreciate help "across the pond" when I do.

Thanks!
