After months, actually years, of resisting my family's desire to check out my forebears, I submitted to one of those companies that takes one's money in exchange for information about one's heritage.
But money's not all they take. They need a bodily fluid. They supply a little vial into which one places said bodily fluid. Then one waits for a long time to get the results. The company I was gently persuaded into using wanted a bit of saliva for their analysis. But I figured most of the time physicians want a sample, it's urine.
I decided to just go ahead in the real world and supply the saliva and wait. I was brought up being told that I was mostly Irish, with 1/16th Cherokee, and Jewish. I'm expecting to discover that I am Chinese, Lithuanian, and Eskimo. It's enough to make a guy spit up, but I'll let you know what they find. I doubt anyone is interested.
