I also would like to know who the parents of O.A. Van Sickle are. In some of the letters and other info that I have, it seems that Oliver had two brothers. One was Johnson J V.S. of which I would like to find out about that line as well, and Charles Van Sickle who married Hannah Baker. I would like to talk to all who are wqorking on this and compare info to see what we can piece together. I have only information on two or three of O.A.'s children out of seven. Look forward to talking to you soon.
