the nobles and adopted “ornamental” surnames as well. Most other naming traditions refer to them as "acquired". They might be given to people newly immigrated, conquered, or converted, as well as those with unknown parentage, formerly enslaved, or from parentage without a surname tradition. Ornamental surnames are more common in communities that adopted (or were forced to adopt) surnames in the 18th and 19th centuries. They occur commonly in Scandinavia, and among Sinti and Roma and Jews in Germany and Austria. Examples include Steinbach ("stone brook"), Rosenberg ("rose mountain"), and Winterstein ("winter stone"). Forced adoption in the 19th century is the source of German, Polish and even Italian ornamental surnames for Latvians such as Rozentāls (Rosental, "rose valley"), Eizenbaums (Eisenbaum, "iron tree"), and Freibergs (Freiberg, "free mountain"). In some cases, such as Chinese Indonesians and Chinese Thais, certain ethnic groups are subject to political pressure to change their surnames, in which case surnames can lose their family-name meaning. For instance, Indonesian business tycoon Liem Swie Liong (林绍良) "indonesianised" his name to Sudono Salim. In this case, "Liem" (林) was rendered by "Salim", a name of Arabic origin, while "Sudono", a Javanese name with the honorific prefix "su-" (of Sanskrit origin), was supposed to be a rendering of "Swie Liong". During the era of the Trans-Atlantic slave trade many Africans lost their native names and were forced by their owners to take the owners' surnames and any given name the owner or slave master desired. In the Americas, the family names of many African-Americans have their origins in slavery (i.e. slave name). Many freed slaves either created family names themselves or adopted the name of their former master. In regions with a strong religious influence, newly acquired names were often given by the religious leaders as part of naming ceremonies. The religion dictated the type of surname but these are traditionally surnames associated with the religion. Islamic names often follow the Arabic patronymic naming conventions but include names like Mohamed or ibn Abihi, "son of his father". Catholic names may have been influenced by the Saint on whose feast day the person was christened, for instance Toussaint and De Los Santos may have been christened on All Saints' Day. As Native Peoples of the Americas were assimilated by the conquering countries, they were often converted to the dominant religion, being christened with associated names (i.e. de la Cruz). Others maintained a
