There is a help guide here for using SP
www.rootschat.com/forum/index.php/topic,43916.0.htmlMain points to remember:
Keep options open on spellings. I tend to only use the wildcard symbol of '*' to pick up on spelling variants. For example, searching for an Isabel, I would normally search for Is*b*l*. Searching for a MacDonald, I would search as M*cDon*.
To help you narrow down options, try IGI first and from there double check on SP. For example, if you do what is called a 'parent search' on IGI, it should show any children to a couple/couples with the names you are searching for. To do a parent search on IGI, from the search screen, just put in parents' full names on the r/h side and then British Isles/Scotland. You can add additional search filters, county and/or time ranges subject to the results you get.
Have a play around, you'll soon get the hang of it!
