Hello - I am descended from Eli Berkey, son of Jacob K. Berkey, son of Jacob Berkey, whose mother was Gertrude Kolb, whose father was Dielman Kolb. DoB for Jacob is Oct 8, 1793 in Lawrence, PA (have been unable to locate which Lawrence). This information comes to me through the Koppes family history book (I only have some photocopied pages). Is this of interest to you? The Berkey's in my family are not, as far as I can tell, descended from Leonard and Mary Burgi from Swiss canton as listed on LDS site. Incidentally, Jacob m. Mary Koppes.
