Here's the problem I always have with doing genealogy research. Some people don't think going with your 'gut' or your 'instincts' is the right way to go because you might end up doing research on the wrong family and I don't just mean one branch but the ENTIRE family back two or three hundred years and then come to find out after all that work that you aren't even related to anyone in the tree.
But I find that using my instincts, genealogical or detective if you prefer, don't just help me find the RIGHT branch or family for my tree but also ends up helping others that might be doing research on the same surname as I am. After all I did find at least two generations of Robinsons for another researcher that turned out not to be mine.
I haven't been doing as much research lately because 'life' has gotten in the way. But I never let my research lag for very long no matter what else is going on. In fact just last week I was poking around trying to find information on a great-aunt's husband's family and sent an email to a cousin (a daughter of the great-aunt) and she gave me a couple of clues. Well, with those few clues I managed to find her GRANDPARENTS marriage record. It turns out her father was born here in the US but was then taken to the Czech republic when he was a baby with his parents and returned to the US when he was about 25. Unfortunately, because the country has changed so much and actually branched out into several other smaller countries finding any other information on that side of the Atlantic is going to be a tough mystery to tackle. But the elation my cousin had when I sent her the image of her grandparent's marriage record was enough for me.
This led me to once again tackle my own maternal side of the tree. Though not as difficult as my cousin's digging through German records when there isn't much known is part of the challenge and much like one of my favorite fictional characters, Nancy Drew, I am always up for a challenge.
