This is what I have for John Nicola. I have that he married first Rachel Mathews who was born 18 Oct 1828 in Preston Co. WV to Joseph and Elizabeth (Cress) Mathews. She came to IA in 1845 and married in Washington Co. on 14 Aug 1856. Some information I have says that Rachel was married first to a Shahan. She died in Washington County on 15 March 1860. John then married Rachel's niece, Nancy Mathews, daughter of William S.and Cassandra (Leach) Mathews. Cassandra was Rachel's sister. Nancy was b. 1840 in Iowa. Nancy married John Nicola in Washington County, 17 May 1860 or June, 1860 in Pilot Grove, Washington Co. IA. I do not have a death date for Nancy.
