Looking for some help. I've been doing research on the early settlers of Sparta, Livingston Co., NY.One of them was Abraham Zerfass along with his wife Hannah Knauss. I'm interested in getting more information on two of their children who married Knauss'.George Zerfass (b. 28 Jan 1805, Lehigh Co., PA; d. 19 Jan 1882, Livingston Co., NY) married Polly Knauss (b 15 Jan 1810, d. 23 Feb 1872, Dansville, NY).Vienna Zerfass (b. 14 Jul 1818, d. 28 Mar 1882) married Henry Knauss (b. 13 Jul 1807, d. 5 Apr 1869).Since George and Vienna are siblings, I am assuming that Polly and Henry Knauss are also siblings, and are related to Hannah Knauss (nephew/niece?).Can anyone confirm this or point me in the right direction?Another possible connection is with through my 4th great grandparents, John Artman (Erdman) and Anna J. Kanouse.Thanks in advance for any help.
