According to this site, http://nfo.net/cal/ts10.html#Sanders , Monte Carlo was his real name. He was the husband of Alma Sanders, who seems to have been prolific from about 1917 on.

"Dinny Danny; The Irish Yacki Hula"
"That Tumble-Down Shack in Athlone"
"Every Tear Is a Smile in an Irishman's Heart"
"By the waters of Killarney"
"Just a bit of Irish lace"
"Two Blue Eyes, One Little Green Isle"
"My Home in the County Mayo"
"The Hills of Connemara"
"The Old Wooden Bridge in Athlone"
Monte Carlo also wrote the complete musical score for the motion picture, "Ireland Today".
He was born in Skamlingsbanke, Gravenstein, Denmark, July 14, 1883 and came to the US in 1906. Biography here: http://www.traditionalmusic.co.uk/music-search/music-songs-composers%20-%200175.
