I really appreciate additions, comments, corrections, questions. I am always trying to get more complete and accurate information.
I belong to the Ulrich and Hans Jurg lines but I also belong to a group trying to pin down the lineage of all the Shellenbergers in the 1850 US census. We have the individuals online on my site at http://www.posom.com/Shellenberger/censussearch.shtml
In the census database, we have codes following those we have linked indicating their lineage. It has been a great help to many people and we hope to move forward in this project. There are 2007 individuals in the 1850 census database; 995 are linked.
