I have an extensive research file of descendants of Michael Dunnigan/Dunagan (b. 1804 Ireland) and his wife Ellen/Eleanor Undersell of Hunter, NY (b. 1806). The 1st generation lived in Hunter, Greene County, NY, then moved to Olive, Ulster County. Children: Mary Ann (m. William VanTassell), John Henry (m. Charlotte VanTassell), Andrew (m. Olive Hornbeck), Michael (m - 1st Jane Hook, 2nd Catherine McKinney), Ellen Elizabeth (m. Joseph Reeves), Lucy (m. Jacob Barley), William (m. Abbie Mayo), Martha Jane (m. Robert Greene), Julie Theresa (m. Thomas Hornbeck), plus an eldest daughter who is so far unknown (b. act 1825/27) Looking to make contact with various family lines.
