This depends on if you are looking for Odd Fellows or Independent Order of Odd Fellows...there IS a difference in researching. The website you are giving is sending me to the UK order and that is not the American branch, where my 3X great-grandfather was a GM. While the societies' objectives are the same, if you are trying to research...you may need to clarify WHICH branch you need to research through. Here is the website for IOOF...
