My 2x great grandfather, Joseph Whimpey came to Australia. His brother, Isaac, became a member of the LDS Church when in Wales, and migrated to the United States with his family, and they lived for a while in Ohio, before the family (except two of his children) moved to Utah.
I have found that the free site Utah Digital Newspapers has been useful in finding newspaper articles for the family. The newspapers they have scanned so far can be found on the What we’ve scanned so far page.
My Whimpey family mainly lived in Utah County, so the papers I have used so far include the American Fork Citizen, Lehi Banner, Lehi Free Press, Lehi Sun, Pleasant Grove Review and the Provo Daily Herald.
