Evelyn Hauer Kerr's known Wigger lineage includes:
- Mathias Wigger, a Catholic man of Kr. Olpe, Helden, Westfalen, Preußen, born by or about 1790. He and his wife Catharina Ronnewinkel were my fourth great-grandparents.
- Maria Elisabeth Wigger, born about 1810. She married Johann Peter Wolfschläger on 24 May 1829 in Helden. They arrived at New York on 16 August 1845 aboard the ship Cotton Planter from Antwerp, Belgium. My third great-grandparents, Johann Peter and Maria Elisabeth settled in Detroit, Michigan.
