I am not relation but I did a little searching on Ancestry.com and found the following information on Michael Erceg:
California Passenger & Crew Lists 1893-1957 includes a Michael Erceg on Ship named Ventura.It departed Aukland 22 December 1906 and arrived in San Francisco California 13 January 1907.
WWI Draft Registration Cards 1917-1918, Roll 1473296 includes a Michael Erceg in Fairbanks Alaska.He was born 29 August 1882 in Austria.He is a mechanic.His nearest relative is John S. Erceg, brother, Aukland, New Zealand.Card is dated October 28, 1918.
1920 US Census, Fairbanks, Fourth Judicial District, Alaska Territory lists a Michael Erceg, age 37, born in Austria.His father was born in Austria and his mother is Ireland.He is single, a gold miner and owns his home.He immigrated in 1897 and was naturalized in 1909.
California Death Index 1940-1997 lists a Michael Erceg, male, birthplace completely unknown, death date 11 March 1962, San Mateo, California.
Fairbanks, Alaska Cemetery Records lists a Michael Erceg, date of birth 1892, date of death 3/11/1962, Pioneer #3, Tier 1, Row 9.Note: This record is a transcription so the date of birth may be incorrect.The record does not state the cemetery just the location but all burials of this time period are in the Clay Street Cemetery (I think).
You may be able to obtain a death certificate from California which should tell what happened to the body.Was it sent back to be buried in Fairbanks?
None of this information states the where he was naturalized but you may be able to find his naturalization record in Alaska or California.
If you would like jpg images of the ship's passenger list, the census and the draft registration card, please let me know.I can email them to you if you give me your address.
