MissScarlett: Something of a mystery man. The <Standard> of September 28th 1896, p.8:<Simultaneously with the tournament at Nuremberg, a National Tournament, under the auspices of the German Chess Association, took place at Eisenach, in which Mr. R. H. Barnes, an Englishman residing at Frankfort, took the first prize. Mr. Barnes is a professor of English, and is very popular at Frankfort; he is President of the Chess Club, and edits a chess column in <Didaskalia>. We give two of his games, played at Eisenach, Mr. Barnes having acquired the title of master by reason of winning the first prize...>
One is his game with Dostal, the other with Ernst Varain.
Definite confirmation is required that this Barnes and the one who played a match with Delmar in America 1880 are one and the same (per his Wikipedia entry). Although that Barnes did indeed lose the match -7 =1, he'd done better the year before:
<The match between Messrs. Barnes and Delmar resulted in favor of the latter. The twelth game was won on Tuesday last by Mr. Barnes; the thirteenth game, on Wednesday, was scored by Mr. Delmar. The final score was: Delmar 7, Barnes 4, drawn 2. Upon the completion of the contest, Mr. Barnes at once challenged his antagonist to play another match on the same terms. Mr. Delmar accepted, and the time will soon be fixed when it shall begin.> (Buffalo Commercial Advertiser, November 11th 1879, p.4)
