My name is Michelle. Somehow in someway most of the Cosmans that you see here are related. Most of us have done extensive research. As far as I know we have been able to trace back our ancestry to Germany. We know that a man by the name of Johannes Kausman came with his wife Barbara to New York from Baden Wurttemberg, Germany about 1750. In 1751 he became a British citizen(because at that time New York was a british colony. He changed his name to John Cosman and so the Cosman family began. In the past 250 years we have descended to many places. I am a direct descendent of Johannes and I live in Toronto, Canada. There are many others as I'm sure you came see from searching the name. I have not been able to trace any info in Germany. Most of the documents there are in German and because the info is limited to mostly church documents. I am interested in searching more there if possible. If you have any questions please feel free to contact me.
