Attempting to trace ancestors of Luther Wentworth a cabinet maker from Indiana that settled in burlington Iowa just before the Civil War. He married Marian (Mirium?) Hutchinson in 1841. His daughter Hattie Mae is my second great grandmother. Luther was awarded two US patents, one for a Gage Lathe in 1855 and one for a Wind Wheel (pumps water) in 1860. I'm pretty clear on descendants, but am stuck tracing ancestors. I've checked the published Wentworth books to no avail.
