The Ronnewinkel surname comes to me via my grandmother, Evelyn Elvina Hauer (Mrs. R. P. Kerr). Her great-great grandmother was:
- [Maria?] Catharina Ronnewinkel, who married Mathias Wigger. She was probably born before or about 1790. The detail above is from the 1829 marriage record of their 19-year-old daughter Maria Elisabeth Wigger. Catharina and Mathias were my fourth great-grandparents.
