RE: so sorry, re: northfield I don't think Northfield Oakwood Cemetery has an address - there is no office there. See the map on the cemetery page for the location. I don't know who is the present record-keeper for the cemetery, but you can contact the Northbrook Historical Society, and the President, Mrs.Hughes, can probably put you in touch.
Thomas & Catherine Pendleton Headstone Thank you for the photo of Thomas and Catherine's Headstone. Catherine's birth and death dates on her headstone enabled me to research and determine the day and month of her birth and death dates, her parents names, and where she was born. I now have this information in my Family Tree and I was able to update her Findagrave Memorial with this information as well.
