The word "ballance" is spelled incorrectly and underlined. My guess is that the clerk copied it exactly the way it was written in the original will and that the underlining is to indicate that--particularly the extra "l."
The original will of Mimke is in the packet of papers and we'll post that later and see if it really is spelled "ballance" on the original. Often that is what notations of that type in a transcription mean.
