I appreciate help because I am very confused. Royal Trees (son of David Caleb Treese and Barzilla Van Zandt) and my grandfather were definitely cousins per both Royal Trees and my grandfather who are both now dead. My Uncle says that grandpa's mother Nancy Elizabeth Bigler and Barzilla Van Zandt were sisters which is not possible unless Nancy was named Sarah as per the 1860 census. Barzilla was born 11-25-1855 (sourced from marriage license, 1860 census and her tombstone) and Nancy 10-11-1859 (source marriage license, tombstone and obituary). Barzilla's parents were John L. Van Zandt (b. abt 1828)and Elizabeth Brown (born abt. 1832) and her siblings per the 1860 census were Margaret b. 1861 and married Thomas Jefferson Treece; Napolean b. abt 1856 married Bethany D. Turner; Nancy C. b. 1866 m. John A. Turner; Isabelle Izora b. 1875 m. Samuel Cavender; and the only possiblility Sarah who was born abt. 1858 so possibly 1859. The other choice would be that she was a sister of David Caleb which is not physically possible because his mother died in 1854. I could really use some help solving this. Thanks, Cheryl Strahm
