I've traced the family tree correctly to 1587 and am currently in the process of adding the names and dates with the sources. The parentage of one individual was incorrect (early 1600s) but I tried to fix the problem by revising the existing parental information instead of adding a new person and then connecting the line to the new person. A rooky mistake. I ended up with a bit of a mess which, thankfully, is now fixed. The original incorrect tree line is fixed with the appropriate people listed in the tree and our tree now has a person with an unknown name at birth listed as I was originally hoping to do.
