[5] The father, himself the son of Dr William Stoker (Senior Physician to the Cork Street Fever Hospital), was "one of the most distinguished of Irish anatomists" and, apparently on account of his prowess in the hunting field, acclaimed "a fine sportsman".

[11] He was in Wanderers' First XV by the beginning of 1886, was second in the club’s drop-kick contest shortly afterwards (kicking an average of 44 yards with both feet), and was elected its captain for the following season.

The last set of that match was "entirely won by the place-volleying and smashing of Frank Stoker who scarcely allowed a ball to pass him at the net", but the pair were outplayed in the final.

[18] Frank subsequently found a new doubles partner in Joshua Pim, a fellow member of Dublin's Lansdowne Club, and the pair began to compete in the annual Irish Championships at Fitzwilliam Square.

[25] After he retained his Irish title in 1895 his tennis career largely came to an end, although in 1896 (as in 1893 and 1894) he represented Ireland against England in both the singles and doubles matches of the international fixture.

He was a winner of the County Dublin Championships and the Fitzwilliam Purse, was runner-up in many singles tournaments (including when defeated by Pim in the 1891 Northern contest), and during the whole of 1892 was the only player to win a match against the reigning Wimbledon champion, Wilfred Baddeley.

[29] He was licensed to practice medicine and surgery by the Irish Royal College in August 1892[30] but, wishing to specialise in dentistry, obtained a place at the recently established Dental School of Guy's Hospital in 1893.
