Yes, your question is simple to answer. When two people have a child and they are unmarried, enter "Not married" for their marriage date, without the quotations. When you set up to do a wall chart, click on "Select Items" and under "Events" make sure there is a check mark next to "Marriage", then under "Event Options" check "Date and place together" or "Date on own line". The Descendants Chart will still show sp: and the name, but underneath that will be M: Not married. The Ancestors Chart will simply show M: Not married. Hope this helps.
