Welcome to altizer.org
Emera (Emmerich) Altizer is the father of the Altizer family. He was baptized on the 8th of April, 1749, in Rhinebeck, Dutchess County, New York. Emera's original name was Emmerich Althauser (Althäuser, Althäusser), and he had several siblings as you can see by viewing his father's geneology page. Emmerich's father, Johann Peter Althauser, came to America from Segendorf, Neuwied, Deutschland (Germany). I have yet to find any proof as to why the name change came about.
As far as I can tell, Johann Peter Althauser came to American at some time between 1724 and 1727. ALTHÄUSSER Anna_Margaretha, *1724 Segendorf (click on the A and scroll down to this listing in the web page frame) was born (in 1724) through Johann's first marriage to Elisabetha Christina [Mittler] (widow of Johann Wilhelm Mittler, from Segendorf). This is verified through German Church records. Then Johann's first child with his new marriage, Maria Elizabetha Althauser, to Elisabeth Catherine Laucks (Emera's mother), was born in 1727 in Dutchess County, New York. Elisabeth Catherine Laucks was born about 1711 in West Camp, New York.
There is conflicting information to be found on the birthplaces of Emera's siblings. The German Geneology site lists Anna Margaretha as being born in Segendorf, and the Western Michigan Geneology site claims that she was baptized (baptisms were common to newborns during this time) in Kingston, New York. Either way, I do believe that Emera Altizer was born in America. I used to believe that he was born in Bingen am Rhein, Deutschland.
