Im Frühjahr 1899 erschienen in der Zeitung „The Singapore Free Press and Mercantile Advertiser“ mehrmals Anzeigen von C. C. J. Wirz, in denen er die Vermittlung von sogenannten Coolies (Kuli, Tagelöhner, vgl. ) anbot. Als Kontaktadresse wurde Queen Road Central in Hongkong angegeben. In keinem weiteren Dokument wird diese Tätigkeit später allerdings erwähnt, aber die klare namentliche Nennung als „C. C. J. Wirz“ sollte als Zuordnung zunächst reichen, zumal seine Frau für 1901 und 1903 Aufenthalte auf den „Philippines“ angibt, so dass ein Aufenthalt in Hongkong glaubhaft erscheint. „My wife and I arrived on the Isthmus on October 10, 1903, by the way of Europe from the far East. […] Soon after our Arrival in Panama  I started a second Hand furniture store, house, room renting and employment agency, and did well for a time.“ (C.C.J. Wirz, 1914) „On October 10, 1903, my husband and I landed at Colon from the Philippines, by the way of Europe.“ (Caroline Wirz) „In May, 1904, General Davis, first Governor of the Zone, and other officials, as well as a number of employees, arrived on the Isthmus. Many of These latter found their way to my Establishment in search of board and lodging, and General Information. When possible I found a place for them, and was useful to them otherwise, for which Services I received very Little cash. As Business conditions were very unfavorable, I entered the Service of the Commission in November, 1904.“ (C.C.J. Wirz, 1914) „We had read in the far off Philippines that the American Government was going to build the Panama Canal, and my husband intended to be one of the canal diggers, and with this object in view, we undertook the Long journey, howewer, as we were ahead of time we started a second-Hand furniture shop, this being something unique then in Panama, and later, when the Americans arrived, we added a Real Estate and Employment Office, and assisted not a few early canal employees to find board and loging, for None of them were overburdened with cash.“ (Caroline Wirz)
https://en.wikipedia.org/wiki/William_C._Gorgas „There are two societies on the Isthmus which tell of the effects of homesickness of the Americans in the employ of the Canal Commission—the Incas, and the Society of the Chagres. The Incas are a group of men who meet annually on May 4th for a dinner. The one requirement for membership in this dining club is service on the canal from the beginning of the American occupation. In 1913 about 60 men were left on the Isthmus of all those Americans who were there at the time of the transfer of the canal property to the United States in 1904.“ (http://www.ajhw.co.uk/books/book398/book398.html)

This was in about 1960. Her dance studio was on the first floor of a building that had the name Rebecca IOOF at its front. The building was along Balboa Road in the area of the police station.“ (https://ufpcmcollection.wordpress.com/2014/11/24/certificate-of-achievement/) Neben dem Wirz Memorial auf der Balboa Road war eine Kirche („… Church of Jesus Christ of Latter Day Saints in Balboa … at the church on Balboa Road next the Wirz Memorial.“, The Panama Canal spillway, 31.
