Why hire a professional? There are many reasons, it could be that you simply need a copy a single document, and the repository is halfway across the country, or that you have reached a dead end and need help. Many family trees are published on the internet or even in print, but without proper documentation it’s difficult to distinguish between what is accurate. A professional can assist with proof standards and proper documentation.
I have a great deal of experience with researching New Jersey history, as well as New England, Italy and England. Many of the practices here are applicable elsewhere.
Try to enjoy your journey for what it is, a puzzle to be solved. Very few of us will walk into a library and pull a book off the shelf and have our family accurately documented. But it’s not the destination, but rather the journey.
I hope you find something useful on my pages.
