Once in a while my enthusiasm for family history collides with a limited amount of research time. That occasionally results in an unfortunate error or two. So it goes with my great grandfather on my mother's side of the family--John W. Slack. In a blog post a few months ago, I erroneously listed his middle given name as “William” thinking I had figured out what the “W” stood for. A few weeks afterwards, I found his correct middle name. How did I manage that? As luck would have it, his death certificate was recently published on-line on a new website I happened to be searching one day. While I have been a little slow to post this discovery (blame it on work), allow me to set the record straight.
