Coming from a poor family, he was the son of Pietro Francescon (born in 1830 in Cavasso Nuovo of Antonio Francescon and Elisabetta Zanussi) and Maria Lovisa (born in 1844 in Cavasso Nuovo of Osvaldo Lovisa and Angela Serena).

Francescon was born in Cavasso Nuovo, a small village in the Province of Pordenone, Italy, and emigrated to the United States in 1890, settling in Chicago.

In 1907, Francescon had contact with the North Avenue Full Gospel Mission, pastored by William Howard Durham, and accepted Pentecostalism.

William Durham had prophesied that Francescon had been divinely appointed to bring the Pentecostal message to the Italian people.

Francescon started churches in Los Angeles, St. Louis, and Philadelphia before departing on missions abroad.
