I stumbled across another genealogy that contained a few “Clough” references. This 1890 book is entitled “The Ladd Family: A Genealogical and Biographical Memoir of the Descendants of Daniel Ladd, of Haverhill, Mass., Joseph Ladd, of Portsmouth, R.I., John Ladd, of Burlington, N.J., John Ladd, of Charles City Co., Va,” and is available on Google Books.
The book references Abial H. Clough, Hannah Clough, Josephine Clough and Sally Clough. While there is some identifying info, there technically isn’t enough at this time without further research to conclusively tie them to the family.
There are also several references to a “John Clough” in the opening pages (pages 1 &2- circa 1639/40). Our immigrant ancestor?
