It is hard to tell exactly as I don't have any dates for Catherine. I only have her listed as living in Wittlaw, WI. Is this anywhere near where your family comes from? I only know that she died in this area in WI but as we know all records are not correct. Sometimes a suburb is listed as a city and vice versa. Do you know of any ships that the Wachal side may have come on? I was told that all persons with the same spelling are related somehow. Others spelt their names with an "el" at the end and they are a different family all together. So I suspect somewhere down the line there is a link.
