"Great-grandma Neill wouldn't let Nellie date the Humke boy because they were related. "
I know someone told me that. I am not dreaming it. I had already known the "Humke boy was related," but the dating (or potential dating) was news to me. I remembered the tidbit while doing something completely unrelated. The problem is that I cannot for the life of me remember who told me. I will write it down now and have to use myself as the source, even though I have no first hand knowledge of it myself.
It is even more frustrating because I was told this little nugget years after I had started genealogy and knew the importance of writing things down as soon as possible.
