On the grounds near the Hippodrome of Can Tunis, their father taught his three sons, Samuel, Enrique (Henry), and Miguel (Júnior) to play football, a sport that was practically unknown in the city at the time.

[10] Together with John Parsons and captain Gustavo Green, the Morris brothers, Samuel as a goalkeeper and Enrique as a forward, played a pivotal role in helping Hispania AC become the very first Spanish club to win an official title, the 1900–01 Copa Macaya, which was the first football competition played on the Iberian Peninsula.

[10] During their time in Hispania, the three Morris brothers joined the ranks of FC Barcelona on two occasions: the first on the occasion of the match against the officers of the British cruise ship HS Calliope on 23 November 1901, where they helped Barça to a 4–0 victory,[10][14] and the second in May of 1902, when they reinforced FC Barcelona during its participation in the Copa de la Coronación (predecessor of Copa del Rey).

[5] After this parenthesis with Barça, the Morris brothers continued to play at Hispania AC until 1903, when the club was dissolved for lack of players, but while Samuel retired due to his advanced age, Enrique and Miguel joined FC Barcelona permanently, playing for the club for two years until 1905, and helping Barça win the Catalan championship in 1904–05.

[3] Later, in the 1909–10 season, he participated in the First Category Championship of Catalonia with the modest Star FC, becoming its captain and later being joined by Miguel.

[10] Morris fought in the First World War as a pilot in the British Royal Air Corps, being shot down and wounded in the abdomen while strafing German positions, although he survived and returned to Spain.
