They moved to Chicago, IL in 1865 and he worked at the boot and shoe trade until 1879 when he was employed as a clerk in the service of the city.

In 1885 McGann was appointed superintendent of streets January 1, 1885, and served until his resignation in May 1891 when he was elected as a Democrat to the Fifty-second and Fifty-third Congresses.

In the 1894 election he was at first named the victor by 31 won votes and was seated in the Fifty-fourth Congress where he served from March 4, 1895, until December 27, 1895.

Hugh R. Belknap, who at first count lost the 1894 election, contested it and after a recount showed he had won, McGann conceded the race without an investigation.
