Another why

Why do I keep coming to dead ends when trying to find my ancestors? Partly it's because poor people didn't leave all that much as evidence for their existence. Partly it's because some of them had such commonplace names, for example Thomas Robinson. There are millions of Thomas fuckin Robinsons. Why couldn't his parents have had the foresight to give him a more findable name? I don't know why I'm so obsessed with finding these people anyway. I bet they were a right bunch of cunts, if their descendants are anything to go by. Grrr.
