Chances are you have run into a few research blocks since you began working on your genealogy project. It happens to even the most ardent researchers!
SOMETIMES YOU DON'T KNOW WHEN TO ACCEPT THAT YOU HAVE TO STOP. That's where someone like me comes in. I can review your entire genealogy project and give you some advice on what you need to work on and how to get around research blocks, if at all possible.
My strongest suggestion is that you give any research path that seems to be blocked a break for a while, or let someone else go over your research. This can be a lot to ask, but if you're willing to do the same for a friend, and you both hold yourself to professional standards, it can help.
There is always more that you can be doing on another line. Sometimes the information you need is coming in its own time. It's a matter of synchronicity. Maybe what you need has been moved around from one archive to another, or is in someone else's hands at the moment. Or you need to meet someone else who will have the answer!
