Tabanus: Lea was a common name that time, and is also not a good search word. I post some tempting options here, but think more evidence is necessary:1860: James Pollard Lea baptized 5 Aug 1860 in Saint Swithin, Worchester (= SW of Birmingham). Parents: James Lea and Elizabeth. (England Select Births)

1890: <There has probably been better play between individual members in the club championship matches than in some of the inter-club encounters. In these Mr. J. P. Lea headed the list with twelve wins and three draws - a formidable score. ... The first partie to be finished was that of Mr. J. P. Lea, probably his sturdiest opponent. The blind-fold player preferred the king's gambit, which Mr. Lea cautiously declined. Mr. Blackburne was early in difficulties, and began to ejaculate, as the amateur announced his moves, "Yes, I don't like this game." His opponent secured a very sharp attack on the king's side before he had time to castle, and a check with the queen placed him in a precarious position. At the fifteenth move Mr. Lea was a pawn ahead, and at the seventeenth he pinned Mr. Blackburne's queen with a bishop, forcing an exchange of the two major pieces, and indirectly winning a rook. Thereupon Mr. Blackburne, recognising the hopeless state of his game, resigned, amid hearty applause for the home player.> (Birmingham Daily Post, 29 Oct 1890)
