In Louisiana - the Alleman (variants Allement, Allemand, Allemond) are generally considered to be of Spanish ancestry.Although the name is often translated meaning "of the Germans" since some of the early settlers located in parishes along the Mississippi River in a region called the German Coast.
Bayou des Allemands was settled in 1721 by Germans under the control of John Law and the company of the Indies.
Juan de Aleman was born / died in Aguimes, Gran Canary, Canary Islands - married abt 1710 to Maria de la Trinidad Zurita.A son, Balthasar (b 3-30-1714 - d abt 1766) born / died in Aguimes, Gran Canary, Canary Islands married on Oct 1, 1736 in the Canary Islands to Antonia Romero Gonzales (b. June 12, 1717 - d ?). Their son, Juan de Aleman Romero was born (Sept 30, 1739) in Aguimes, Gran Canary, Canary Islands and died in Assumption Parish, LA abt 1819.
Many other "Alleman" descendants consider Louisiana their home.Most people in Louisiana associate the Alleman ancestry as Cajun or French because the predominant (or primary) language spoken years ago was French.
