Looking for any info on my grandfather, Nels Deerfield, born in Denmark in 1859. Came to America, married my grandmother Jennie in Wisconsin about 1889. Jennie came from Madison Wisconsin. Don't have a maiden name for her. They moved to Iowa, where my father Bayard and his sister Rachel were born. I believe they may have been born in Exira, Iowa. My grandfather changed his last name to Deerfield, when he arrived in America. It may have been Diremark. Not sure of the spelling.
