Answer by taking a quote from the following article:

Barrow was born in Springfield, Illinois, the oldest of four children, all male, born to Effie Ann Vinson-Heller and John Barrow. Barrow's father fought in the Ohio Volunteer Militia during the American Civil War. Following the war, Barrow's parents, with John's mother, brothers, and sisters, traveled in a covered wagon to Nebraska; Barrow was born on a hemp plantation belonging to relatives during the trip. The Barrows lived in Nebraska for six years before moving to Des Moines, Iowa.

Barrow partnered with Harry Stevens in 1894 to sell concessions at baseball games. He helped George Moreland form the Interstate League, a Class-C minor league, in 1894. Barrow, with Stevens and Al Buckenberger, purchased the Wheeling Nailers of the Interstate League in 1896. Barrow served as field manager until the collapse of the league that season. The team continued in the Iron and Oil League for the rest of the year.  Barrow then bought the Paterson Silk Weavers of the Class-A Atlantic League, managing them for the rest of the 1896 season. Barrow discovered Honus Wagner throwing lumps of coal at a railroad station in Pennsylvania, and signed him to his first professional contract. Barrow sold Wagner to the Louisville Colonels of the National League (NL) for $2,100 the next year ($61,774 in current dollar terms). With poor attendance, Barrow brought in professional boxers as a draw: he had James J. Corbett play first base while John L. Sullivan and James J. Jeffries umpired. He also hired Lizzie Arlington, the first woman in professional baseball, to pitch a few innings a game.  From 1897 through 1899, Barrow served as president of the Atlantic League. During this time, in the winter of 1898-99, Barrow and Jake Wells established a movie theater in Richmond, Virginia. Barrow managed Paterson again in 1899, but the league folded after the season.  With the money earned from the sale of the Richmond movie theater, Barrow purchased a one-quarter share of the Toronto Maple Leafs of the Class-A Eastern League in 1900 from Arthur Irwin, and served as the team's manager. Irwin, hired to be the manager of the Washington Senators of the NL, brought his most talented players with him. Rebuilding the Maple Leafs, Barrow acquired talented players, such as Nick Altrock, and the team improved from a fifth-place finish in 1899, to a third-place finish in 1900, and a second-place finish in 1901. The Maple Leafs won the league championship in 1902, even though they lost many of their most talented players, including Altrock, to the upstart American League (AL).  Barrow managed in the major leagues with the Detroit Tigers of the AL in 1903, finishing fifth, a thirteen-game improvement from their 1902 finish. With the Tigers, Barrow feuded with shortstop Kid Elberfeld. Tigers' owner Sam Angus sold the team to William Yawkey before the 1904 season. Barrow managed the Tigers again in 1904, but unable to coexist with Frank Navin, Yawkey's secretary-treasurer, Barrow tendered his resignation. He then managed the Montreal Royals of the Eastern League for the rest of the season. He managed the Indianapolis Indians of the Class-A American Association in 1905 and Toronto in 1906. Disheartened with baseball after finishing in last place, Barrow hired Joe Kelley to manage Toronto in 1907, and after signing the rest of the team's players, became manager of the Windsor Arms Hotel in Toronto.

Did he change teams?
in 1894. Barrow, with Stevens and Al Buckenberger, purchased the Wheeling Nailers of the Interstate League in 1896.
