I looked up your names in my files of RENWICKs in America that I have collected over the years. I could not find a match. But I was interested in your family, especially the parents. I have RENWICK ancestry from Scotland who lived in New York then moved to Illinois. My 3rd gt grandfather is George RENWICK born 12Feb1806 in Scotland. I have found a good match to the family of Robert RENWICK and unnamed wife of Unthank, Hobkirk parish, Roxburghshire. It seems many RENWICKs came from Roxburghshire in Scotland.
