I'm not sure this will be of any help to you but I have a William Urwin, born in Northumberland, England,June 10, 1820. Married to Ellen Winless, in Durham, England, September 6, 1839. Came to Americal in 1850. If this sounds like someone you are looking for. I found a short Bio, in the Biography of William Urwin,in a book titled "History of Nebraska Volume 1" Published in 1889 by Chapman bros. You can email me directly at firstname.lastname@example.org and I will write the whole biography out for you. Barbara.
