I amaware of the spellings. The actual correct spelling is as you list Vaccaiani. My maingoal is to find present days descendants. Inow have some information leading me to believe they lived north of Buenos Aires as I have found some families by that name in Zarate.I am in the process of contacting them. I was more interested in possibly finding some vital records for the period 1920's -2000 or some genealogical surnamespostings on Argentine sites. I have a very detailed account of this family in Italy and photos and names of the ones who went to Argentina.
