Hi Glenda ! A couple things: First if you go to this web site - http://iagenweb.org/chickasaw/ - and enter NATVIG into the search box you will get a couple items on that surname. Also, if you go to this web page - http://iagenweb.org/chickasaw/surnameindex4.htm - and follow those instructions you can get the surname list published for others to see. I hope these suggestions can help. Do you have some dates, sibling, wife, children names? Do you think Ole is Ale? In 1937 there is an Ole Natvig who received losses due to a fire. Sincerely, Mike
