Near-names

When Larry first succeeded in his effort to get me interested in Hesch genealogy, I remembered a pioneer cemetery south of the Janson farm.  When we lived in Buckman, that little cemetery was overgrown with bushes and weeds, but in the spring it was almost carpeted with naturalized iris.  It was eye-catching and was probably the reason I was aware of it.
When I made a point of stopping there 2-3 years ago, I was startled to find monuments with the name BESCH.  Was this a mistake?  Couldn't be--there were a few of them, not just one.  Since then, we've found other references to the Besch family, who settled near Dixville.  (I believe the person who was killed when the Buckman mill boiler exploded was a Besch).  But Besch is close to Hesch.
As Larry and I peruse lists, websites and books for Buckman names, we've been struck by how many other 'near-names' there were in our little area.  They were different by one or two letters and by pronunciation...I wonder if this is a unique Morrison thing?
