I thought that was it at first, but changed my mind, but could not delete post. Maybe can you put up some more of the text for comparative analysis? Especially if you have the sequence рѣ (r plus yat'). It looks like the writer made an error and overwrote something there.

So far I am guessing Варѣ_ка (the writer makes his к without connecting the vertical with the two legs). See Мазуркевичъ in the next line.
