Duncalf in Wisconsin

Thomas Duncalf and his wife, Ann (Jackson) of Macclesfield, Cheshire, England emigrated in 1865 via New York to Lancaster, Grant, Wisconsin. They brought with them six children and a seventh was born in Lancaster. One of their descendants, a grandson Frederick Duncalf, became a professor at Texas University, his speciality being Medieval English History. He appears to have had no children.

I have deails of this family in England back to the 16th century and would like to hear from descendants or anyone researching the name Duncalf.
