    I have a few business letters, bills of sale and correspondence addressed to; Jack Anderson, J M Anderson, Andrew Anderson, and Henry Anderson all with Atlantic mailing addresses. Dated between 1898 and 1900. Do you want them? I found them among papers of my deceased parents Frank and Rosemary Gorman and the papers of Richard and Katherine Ann Worley, my maternal grandparents. All were residents of Atlantic at one point. I do not know their relationship to the Anderson family, or why they had possession of the papers.
