Tina, I have often done that over the years. It can be frustrating when you cannot seem to move forward. The best thing to do is put the research down and pick up another line and with fresh eyes begin reviewing your notes and see if new ideas emerge.
I was visiting Find A Grave to look at my great-grandmother's stone. Since my last visit, somebody had added her obituary. It contained her father's name. I have been looking for this for years! A name like Hunt is not rare, so it's been a long journey looking for this one!
