Who is the tallest of them all? (Average Height by Last Name in Udbina region)

I am one of 5 brothers and am the shortest (or at least tied for being the shortest among them).  And I stand at 6'5".   Because I am curious to see where that height comes from, I wanted to look at the the average height by last name.  For this little exercise I only included the 54 families for which we had the height for at least 10 people.   Here's the height distribution for that group:

As you can see there is only about 3 inches of difference between the shortest and tallest).  I can trace my roots back to at least 4 of the names in the area (Ilich, Djakovich, Klaich, and Opalich).  These four all make a respectable showing. The Klaich and Opalich family are about average and the Ilich and Djakovich are above average.  In fact, the Djakovich at the top of the distribution.  So this may mean that the family's height came through Sofia Ilich (Dad was an Ilich and mom was a Djakovich).

 Here's the full list, sorted by the average height for the given family.
