My husbands great great grandmother was Julianna A. Blough 1830/1900 Married John John J. Keiser b/1826 Somerset Co. Pennsylvania.
I also have a book called "A Compilation of the Blauch-Blough-Plough-Blouch- Family"
History and Genealogy. Written by Rev. Herbert R. Blouch, S.T.W. amd Mildred C. Blouch. Written in 1980 I believe I bought the last copy printed about 5 years ago. I would be glad to help or share. It is quite lengthy Being that there are so many many spellings of the name it is the most confusing family ever. You can reach me off line.
