Hi Lynne, The following URLs are for the Jones County Iowa web site. On the first site you will find a biography for William Condit, son of Alvin P. Condit and the following site displays the 1856 census and list Alvin and Maria's children.
I hope this helps. I have a few other "tid-bits" of information you may be able to use. Maybe we can share information in the furture, The Jacobus families of Iowa/Ohio and points east seem to be difficult to track. I will appreciate any thing you may have to share. Catch me at Manncv@juno.com.
