I am sorry if I offended you. I do not understand how I did this: I do not have any other concerns here than the whereabouts of the person I am looking for. The site you suggested I visited, of course, but searching freely in their database did not give any result. Clicking on the British flag did not provide any info on costs for sending information, nor on CEMLA, which is not to be found among the links Familias Argentinas provides to 'Genealogy webs'. But the links gave me the idea to look further on the internet for 'inmigración'+ Argentina,and so I found CEMLA, to learn that who wants further information on a search result has to fill in an form, and "Envíe en un sobre este formulario  junto con un comprobante de depósito de $18 a la siguiente cuenta: Congregación de los Misioneros de San Carlos Borromeo (Scalabrinianos), Banco Galicia" etc. Of course these 'dollars' will be Argentinian pesos: 5.3125 of them today make one Euro, so $ 18 = € 3,40. Foreigners can make contact through e-mail and "Only if the requested last names are contained [in the available passenger lists]", are asked to "please pay 17€ to the following [Italian] account: [of the] Casa Generalizia della Congregazione dei Missionari di San Carlo – Scalabriniani. (Elsewhere I saw mentioned the amount of Euro 20 when using a German Roman Catholic channel). For this fee of € 17 or Pesos $ 90,3 you then "In case of an exact match, () will receive by mail Certificado de Arribo a América (certificate of arrival)." So far about the costs involved. Do I need to speak Spanish to understand that in charging foreigners a holy miracle seems to happen?!! I do read some Spanish, but it escapes me how"my concerns" are being spared by reading this article by Gerardo Young in Clarín of November 16 last year: Los expedientes perdidos del Archivo de los Inmigrantes (http://www.clarin.com/diario/2008/11/16/um/m-01804180.htm ). Two quotes: "() en esas miles, millones de cajas de cartón que, descuidadas, una sobre la otra, se acumulan sin lógica ni destino aparente con la información de cada uno de los argentinos y extranjeros que han entrado o salido del país alguna vez." and: "En la Direccion de Migraciones admiten el caótico estado del archivo, cuyo inventario no existió jamás ni se está realizando".
But it was a pleasure to hear from you. Maybe you will tell me what escaped my notice: although Argentina and the Netherlands became somewhat closer during recent years, the distance still is very great... Willem K.
